A young guy just graduating college scored a good job and has a job that will allow him to buy a new car.he was heartbroken to find out the tesla roadster is out of his price range and out of production.he lives near a tesla dealership and has been a fan of the idea of an electric car, but he is not sure it would work for him.he needs your help in evaluating decision. He drives about 20,000 miles a year, and his commute to work is 30 miles each way and was thinking he could even keep his 1998 pontiac sunfire around as a second.it only costs about 300$ a year to keep insurance on the sunfire.he was surprised that the insurance and related fees were really pretty much the same.he knows he will be bound by the 300 miles range of the electric , but he likes the idea of them. If he gets a Tesla, he will plan on just keeping the sunfire too.an added benefits of going with the Buick is that he could just have one car around.if it would meet his needs, he is willing to rent a car if he goes on a long trip. 1) Which is cheaper?is it financially better to keep the sunfire around and get a tesla S, or should be get the buick? 2) If he was to finance his new car purchase a 0 % interest for four years, what is the total cost of fuel/power, vechile, and oil changes at 5,000 miles? 3) His garage has a 15amp 120 volt plug, but for $750 he could get a 50 amp 220 plug added.Tesla claims 48 hours charging time for 15 amp plug in and a 50 amp plug in.is it worth the cost and can be save enough to justify this extra cost if he goes electric. Here is the information he has to compare the two cars. Tesla mOdel S 4 door 85 k Wh battery 85

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.
