You are given the sample mean and the population standard deviation. Use this information to construct the​ 90% and​ 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If​ convenient, use technology to construct the confidence intervals.

A random sample of 35 home theater systems has a mean price of ​$144.00. Assume the population standard deviation is $15.90.

A. Construct a 90% confidence interval for the population mean.

Suppose there is a movie theater who charges ticket based on ages. Less than 3 years old, free; between 3 to 12, $10; more than 12 years old, $15. Please design a program with loop to,

1) Ask the name then age of the audience,

2) Based on audience's input, tell the audience (with the person's name) how much is the ticket,

3) Stop the program when type in 'quit' in your program.

Humana Hospital Corporation installed a new MRI machine at a cost of $750,000 this year in its medical professional clinic in Cedar Park. This state-of-the-art system is expected to be used for 5 years and then sold for $125,000. Humana uses a return requirement of 25% per year for all of its medical diagnostic equipment. As a bioengineering student currently serving a coop semester on the management staff of Humana Hospital Corporation in Louisville, Kentucky, you are asked to determine the minimum revenue required each year to realize the expected recovery and return. In short, you need to estimate first the capitol recovery and then the annual worth.

You are looking into a factory to make strained peas. You estimate that the equipment will cost $50,000, which you would depreciate over the 10-year life of the project to a book value of zero. The salvage value of the equipment is zero. You think you can sell 15,000 cans at $2/can. The cost of producing the cans is $0.80 each. Your tax rate will be 40%. You plan to maintain an inventory equal to 25% of revenues and you can salvage 80% of this working capital at the end of the project’s life. You plan to use your garage, which means you will have to pay $2,000/year to park your car elsewhere (the good news is that the $2,000/year is tax-deductible). To estimate the cost of capital for the project you look at the following comparable firms:

The Fairmont Hotel in San Francisco needs to replace its air conditioning system. There are two alternatives, both of which can do the job equally well:

The relevant discount rate is 10% and the marginal tax rate is 35%.
