Lab on Confidence Intervals The story: Studies have shown that the random variable X, the processing time required to do a multiplication on a new 3-D computer, is normally distributed with mean and standard deviation 2 microseconds. A random sample of 16 observations is to be taken (i.e. 16 random multiplications will be performed and the time that it takes to perform each one of them will be annotated). The sample mean will be calculated. Part 1- The very basics 1. Before we collect the random sample, what can we say about the sampling distribution of ? 2. Before we collect the random sample, what is the probability that the sample mean will have a value that is greater than or equal to , and less than or equal to In other words, what is the probability that the sample mean is within 0.98 microseconds ( ) of the true (unknown) mean time? 3. A random sample was taken (i.e.16 multiplications were done) and the processing times were as follows: 42.65 45.15 39.32 44.44 41.63 41.54 41.59 45.68 46.50 41.35 44.37 40.27 43.87 43.79 43.28 40.70 Round the times to the nearest tenth (e.g. 42.65 ~ 42.6) and do the stem-and-leave display Do the stem and leaf display. Calculate the sample mean 39 40 41 42 43 44 45 46 4. Now we will use our knowledge of the value of the sample mean for this particular sample and the relationship between sample means (in general) and population mean (see questions 1 and 2 of this lab) to make an intelligent guess (estimation) of the population mean. Use the formula to calculate a 95 % confidence interval for the population mean (Show your work) ( , ) From the Minitab menu, use STAT>BASIC STATISTIC>ONE SAMPLE Z to check your calculations. Calculate the width of the confidence interval _______________ 5. Interpret the confidence interval you just found: We are 95% confident that the true mean processing time required to do a multiplication on a new 3-D computer lies between __________ and __________ microseconds. (The meaning of this is the following: Think of all the possible samples (all the possible sets of 16 multiplications) that we could have been done with this type of computer; 95% of those samples would have produced confidence intervals that contain the true mean, the other 5% would have been off)

He argues that in order to become more efficient, we need to put everyone in the same workhouses and eliminate division. C. He says that the division of labor provides farmers with the opportunity to become involved in manufacturing. D. He means that each person makes one small part of a good very quickly, but this is bad for the quality of production overall. E.

It suggests that there could be a natural harmony of interests among states because they can divide labor among themselves to the benefit of everyone. B. It suggests that states can never be secure enough to cooperate because every state is equally capable of producing the same things. C. It suggests that a central authority is necessary to help states cooperate, in the same way that a manager oversees operations at a factory. D. The allegory of the pins is a great way to think about how wars come about, because states won’t cooperate with each other like pin-makers do. E. The allegory of the pins shows us that there is no natural harmony of interests between states. Smith sees the development of industry, technology, and the division of labor as A. generally positive but not progressive. The lives of many people may improve, but the world will generally stay the same. B. generally positive and progressive.

According to Rosling, how are regional statistics about child survival rates and GDP potentially misleading? A. Countries have an incentive to lie about the actual survival rates because they want foreign assistance. B. Statistics for the individual countries in a region are often vastly different. C. Regional statistics give us a strong sense of how we can understand development within one region, but it does not allow us to compare across regions. D. The data available over time and from countries within regions is often poorly collected and incomplete. E. Child survival rates cannot be compared regionally, since each culture has a different sense of how important children are. What is Rosling’s main point about statistical databases? A. The data is available but not readily accessible, so we need to create networks to solve that problem. B. The data that comes from these databases is often flawed and unreliable. C. It doesn’t matter whether we have access to these databases because the data can’t be used in an interesting way. D. Statistics can’t tell us very much, but we should do our best to make use of the information we do have. E. The information that could be true is too hard to sort out from what isn’t true because we don’t know how strong the data really is. http://www.marxists.org/archive/lenin/works/1916/imp-hsc/ch10.htm#v22zz99h-298-GUESS Click the link at left to read Chapter 10 of Imperialism, The Highest Stage of Capitalism, then answer the questions below.

11/3/2015 1 CourseWork CAPE 2030 Process Systems and Applications Part II: Principles of Flow Measurement and Process control Notes for Part II Course Work One assignment should be independently completed and submitted. The course work must be typed with word processing software and submitted in the format of either WORD or PDF. All figures must be drawn by the submitter. Electronic scanned texts, equations or figures are not acceptable, except the use in appendix. No tolerance will be given to plagiarism. The deadline for the submission of the course work is, 23:59 (midnight ), Monday, 23rd November 2015 ASSIGNMENT : Counter-gravity Slurry Flow Measurement and Auto-control System The objectives of the project are to create a solid mass flowrate measurement and automatic volumetric flowrate control system in the inclinable slurry flow test bed in G56 laboratory (Figure 1). The project is to use the existing electromagnetic flow meter (EMF), add one flow density meter (FDM, based on differential pressure measurement) to the vertical section of and one hydraulic automatic slurry control valve (ACV) to the existing flow test bed in G56. One appropriate automatic control strategy (in single loop feedback control) will be applied to achieve the required precision less than 1% of maximum slurry flowrate. The EMF will measure the volumetric flow rate of the slurry. The FDM will give the density of flow mixture and the ACV will execute the control of the slurry flow in the automatic control system (ACS). It is known the internal diameter of the pipeline is 0.05 m; the required range-ability of slurry volumetric flow measurement is from 0.196×10-3 m3s-1 to 7.85×10-3 m3s-1 in regard to flow velocity from 0.1 ms-1 to 4.0 ms-1 and the demanded maximum controllable slurry flowrate is 2.5×10-3 m3s-1 with turn-down ratio at 10. The slurry feed-in is treated as a wild flow with the solid concentration up to 20%, specific density 2.4 and size distribution from 50 to 400 m. The internal energy conversion and the slip velocity between two phases (solid and water) are assumed ignorable.

Q1 A machining center in a local manufacturing company has five jobs to complete. The jobs are labeled 1, 2, 3, 4, and 5 based on the order they entered the shop. Your manager has asked you to compare two different job sequences to determine the best order for processing the jobs – First-In, First-Out (FIFO) and Shortest Processing Time (SPT). Compare the two sequences. Which sequence would you recommend and why? Be sure to include a variety of measures (average completion time, lateness, etc.) to compare the two sequencing rules. Include all calculations in your response q2 You work for a healthcare insurance company as an industrial engineer. As part of the company’s customer service department, there is a call center that responds to customer questions by phone. Your manager has asked you to perform an analysis of some data that the call center has collected over the last two years in an effort to determine how many workers are needed. In particular your manager wants to find out if there is a relationship between how long it takes to answer a call (independent variable) and whether or not customers will hang up (dependent variable). Is there a linear relationship between these two variables? Include a graph and analysis to support your opinion. If the goal of the call center is to have fewer than 15% of calls abandoned, how quickly must the call center respond? Learning Outcome #2. Data for Question 3 Average Answer Speed = Average number of seconds to answer an incoming call during the week % abandoned = % of calls that are abandoned (hang up) before being answered during the week. let me know if you can do excel work so I can send you the rest of the information and date
