Take Home Exam 3: Special Note Before Starting the Exam: If you scan your solutions to the exam and save it as a pdf or image file and put it on dropbox and I can not read it or open it, you will not receive credit for the exam. Furthermore, if you write the solutions up in word, latex ect. and give me a print out, which does not include all the pages you will not get credit for the missing pages. Also if your folder on dropbox is not clearly labeled and I can not find your exam then you will not get credit for the exam. Finally, please make sure you put your name on the exam!! Math 2100 Exam 3, Out of Class, Due by December 8th, 2015 at 5:00 pm. Name: Problem 1. (15 points) A random variable is said to have the (standard) Cauchy distribution if its PDF is given by f (x) = 1 π 1 1+ x2 , −∞< x <∞ This problem uses computer simulations to demonstrate that a) samples from this distribution often have extreme outliers (a consequence of the heavy tails of the distribution), and b) the sample mean is prone to the same type of outliers. Below is a graph of the pdf a) (5 points) The R commands x=rcauchy(500); summary(x) generate a random sample of size 500 from the Cauchy distribution and display the sample’s five number summary; Report the five number summary and the interquartile range, and comment on whether or not the smallest and largest numbers generated from this sample of 500 are outliers. Repeat this 10 times. b) (5 points) The R commands m=matrix(rcauchy(50000), nrow=500); xb=apply(m,1,mean);summary(xb) generate the matrix m that has 500 rows, each of which is a sample of size n=100 from the Cauchy distribution, compute the 500 sample means and store them in xb. and display the five number summary xb. Repeat these commands 10 times, and report the 10 sets of five number summaries. Compare with the 10 sets of five number summaries from part (a), and comment on whether or not the distribution of the averages seems to be more prone to extreme outliers as that of the individual observations. c) (5 points) Why does this happen? (hint: try to calculate E(X) and V(X) for this distribution) and does the LLN and CLT apply for samples from a Cauchy distribution? Hint: E(X) is undefined for this distribution unless you use the Cauchy Principle Value as such for the mean lim a→∞ xf (x)dx −a a∫ In addition x2 1+ x2 dx = x2 +1−1 1+ x2 dx = 1− 1 1+ x2 " # $ % & ' ∫ ∫ ∫ dx 1 1+ x2 dx = tan−1 ∫ x +C Problem 2. (5 points) A marketing expert for a pasta-making company believes that 40% of pasta lovers prefer lasagna.

(10 points) A coin is tossed 20 times, resulting in 5 heads. Is this sufficient evidence to reject the hypothesis that the coin is balanced in favor of the alternative that heads occur less than 50% of the time (essentially is this significant evidence to claim that the coin is unbalanced in favor of tails)? Use a 0.05 level of significance. Problem 4. (25 points) Since the chemical benzene may cause cancer, the federal government has set the maximum allowable benzene concentration in the workplace at 1 part per million (1 ppm) Suppose that a steel manufacturing plant is under investigation for possible violations regarding benzene level.

Assume normality of the population from which the samples were drawn. a) (3 points) What is an appropriate null hypothesis for this scenario? (Give this in symbols) b) (3 points) What is an appropriate alternative hypothesis for this scenario? (Give this in symbols) c) (3 points) What kind of hypothesis test is this: left-tailed, right-tailed or two-tailed? Explain how you picked your answer. d) (3 points) Is this a one-sample t-test or a one-sample test using a normal distribution? Explain how you picked your answer. e) (4 points) If the test using this sample of size 14 is to be done at the 1% significance level, calculate the critical value(s) and describe the rejection region(s) for the test statistic. Show your work. f) (5 points) OHSA finds the following for their sample of size 14: a mean benzene level of 1.51 ppm and a standard deviation of 1.415 ppm. What should be concluded at the 1% significance level? Support your answer with calculation(s) and reasoning. g) (4 points) Calculate the p-value for this test and verify that this answer would lead to the same conclusion you made in part f. Problem 5. (15 points) A normally distributed random variable Y possesses a mean of μ = 20 and a standard deviation of σ = 5. A random sample of n = 31 observations is to be selected. Let X be the sample average. (X in this problem is really x _ ) a)(5 points) Describe the sampling distribution of X (i.e. describe the distribution of X and give μx, σx ) b) (5 points) Find the z-score of x = 22 c) (5 points) Find P(X ≥ 22) = Problem 6. (10 points) A restaurants receipts show that the cost of customers' dinners has a distribution with a mean of $54 and a standard deviation of $18. What is the probability that the next 100 customers will spend a total of at least $5800 on dinner? Problem 7. (10 points) The operations manager of a large production plant would like to estimate the mean amount of time a worker takes to assemble a new electronic component. Assume that the standard deviation of this assembly time is 3.6 minutes and is normally distributed. a) (3 points) After observing 120 workers assembling similar devices, the manager noticed that their average time was 16.2 minutes. Construct a 92% confidence interval for the mean assembly time. b) (2 points) How many workers should be involved in this study in order to have the mean assembly time estimated up to ± 15 seconds with 92% confidence? c) (5 points) Construct a 92% confidence interval if instead of observing 120 workers assembling similar devices, rather the manager observes 25 workers and notice their average time was 16.2 minutes with a standard deviation of 4.0 minutes. Problem 8. (10 points): A manufacturer of candy must monitor the temperature at which the candies are baked. Too much variation will cause inconsistency in the taste of the candy. Past records show that the standard deviation of the temperature has been 1.2oF . A random sample of 30 batches of candy is selected, and the sample standard deviation of the temperature is 2.1oF . a. (5 points) At the 0.05 level of significance, is there evidence that the population standard deviation has increased above 1.2oF ? b. (3 points) What assumption do you need to make in order to perform this test? c. (2 points) Compute the p-value in (a) and interpret its meaning.

10. Which of the following statements is CORRECT? a. The proper goal of the financial manager should be to maximize the firm’s expected cash flows, because this will add the most wealth to each of the individual shareholders (owners) of the firm. b. The financial manager should seek that combination of assets, liabilities, and capital that will generate the largest expected after-tax income over the relevant time horizon. c. The riskiness inherent in a firm’s earnings per share (EPS) depends on the characteristics of the projects the firm selects, which means it depends upon the firm’s assets, but EPS does not depend on the manner in which those assets are financed. d. Large, publicly-owned firms like AT&T and GM, are controlled by their management teams. Ownership is generally widely dispersed, hence managers have great freedom in how they manage the firm. Managers may operate in stockholders’ best interests, but they may also operate in their own personal best interests. As long as managers stay within the law, there are no effective tools that can be used to motivate them to take actions that are in the stockholders’ best interests. e. Potential conflicts of interest can exist between stockholders and managers, and also between stockholders and bondholders.

Line boundary helps locating starting and ending words. • Apply Ankur Patwa’s character frequency tool to obtain the frequencies of uni-gram, di-gram, tri-gram, quad-gram in the ciphertext. Then try to generate a monalphabeic mapping using natural language statistics in viewgraph 10 of basic crypto. Normally we start by guessing the high frequency tri-grams and quad-gram. You can verify the correctness of the mapping by cross referencing among the quad-gram, tri-gram, di-gram, uni-gram, and also the starting words and ending words of a line. • On viva, use “monosub.pl <ciphter.txt> <mapfile.txt> <workfile.txt>” to geneate the current mapping. monosub.pl is available at /home/cs591/public_html/crypto/src. You can copy the monosub.pl to your directory or use /home/cs591/public_html/crypto/src/monosub.pl • Try to guess and validate as many mappings as possible, say top 4, before you proceed with monosubstituion. • Once you get the working file, try to separate word boundaries to bring out additional mappings. About 4 rounds of mapping you should be able to decipher it. • Document the key mappings, your observations (how you derive the next mappings), and intermediate cipher results.

Homework #2: Cryptoanalysis on Monoalphabetic Ciphertext Goal: • Understand basic cipher and apply natural language statistics to decipher text encrypted using monoalphabetic cipher.

Question 12 (1 point) Research finds that happiness with one’s relationship is related to having a partner who is Question 12 options: masculine or androgynous. feminine or androgynous. masculine if a male, feminine if a female. masculine if you are masculine, feminine if you are feminine. Question 13 (1 point) In the original learned helplessness model, people were said to experience learned helplessness when they Question 13 options: encounter obstacles they cannot overcome. encounter aversive events. generalize their inability to control one aversive event to a situation they might be able to control. give up trying after they realize they can’t do anything about an aversive situation. Question 14 (1 point) Researchers investigating the observational learning of gender role behaviors find that boys imitate male models instead of female models Question 14 options: as soon as they develop an identity as a male. after they noticed that a certain behavior is performed more by one gender than the other. more often than girls imitate female models. but that the opposite is not found for girls. Question 15 (1 point) The androgyny model of gender-type divides people into how many different groups? Question 15 options: two four six eight ________________________________________ . ________________________________________ Question 1 (1 point) The cognitive approach has been criticized in which of the following ways? Question 1 options: It does not fit well with current trends in psychology. The research has given it little support. It is too specific and needs more abstraction. It is not needed to explain individual differences in behavior. Question 2 (1 point) All of the following techniques are methods used by Kelly in psychotherapy except one. Which one? Question 2 options: asking people about their personal constructs asking people to describe their ideal self asking people to define their personal constructs forcing people to attend to their process of construing the world Question 3 (1 point) One study the self-schema presented students with 40 questions for which they pressed Yes or No. The researchers found that participants were more likely to remember the information when WA.the words had the ability to generate emotions. Question 3 options: participants were asked about a rhyme. a self-referent question was difficult to answer. the question was processed about the participants themselves. Question 4 (1 point) Which of the following was advocated by George Kelly? Question 4 options: People are largely controlled by the environmental stimuli they encounter. People are motivated to make sense out of all the stimuli that impinge on them. People are happier when they accept that life is full of unexpected turns and surprises. Most of what determines our behavior is not readily accessible to consciousness. Question 5 (1 point) Participants in one study were divided into those with and without a well developed “independence” schema. Later participants were asked about their own level of independence. Compared to aschematics, participants with a strong independence schema Question 5 options: took longer to answer because they had more information to process. took longer to answer because it was more important to them to give a correct answer. took less time to answer. took the same amount of time to answer, but were more confident of their answers.
