QUESTIONS NUMBERS 6 - 8 HAVE COMMON INFORMATION ON NEW PROJECT Lowell Inc. projects unit sales for a new project with a life of FOUR YEARS as follows: Year Unit Sales 1 10,000 2 12,000 3 14,000 4 16,000 Production will require Lowell must have an amount of NOWC on hand equal to 7 percent of the upcoming year’s sales. Total fixed costs are $100,000 per year, variable production costs are $220 per unit, and the units are priced at $300 each. The sale price and variable costs will increase by 2 percent every year. The equipment needed to begin production has an installed cost of $2,000,000. The equipment qualifies as 5-year MACRS property. Years 1 2 3 4 Depreciation rate 20% 32% 19% 12% In FOUR years, this equipment can be sold for about 19 percent of its acquisition cost. Lowell is in the 25 percent marginal tax bracket and has a required return on all its projects of 18 percent. Based on these preliminary project estimates, what is the IRR of the project? 11.40% 12.05% 22.55% 17.17%

Use the standard normal distribution or the t-distribution to construct a 95% confidence interval for the population mean. Justify your decision. If neither distribution can be used, explain why. Interpret the results. In a random sample of 12 mortgage institutions, the mean interest rate was 3.57% and the standard deviation was 0.36%. Assume the interest rates are normally distributed. Which distribution should be used to construct the confidence interval? A. Use a normal distribution because n < 30 and the interest rates are normally distributed. B. Use a t-distribution because it is a random sample, $\sigma$ is unknown, and the interest rates are normally distributed. C. Use a normal distribution because the interest rates are normally distributed and $\sigma$ is known. D. Use a t-distribution because the interest rates are normally distributed and $\sigma$ is known. E. Cannot use the standard normal distribution or the t-distribution because $\sigma$ is unknown, n < 30, and the interest rates are not normally distributed. Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice. A. The 95% confidence interval is ( (Round to two decimal places as needed.) B. Neither distribution can be used to construct the confidence interval. Interpret the results. Choose the correct answer below. A. It can be said that 95% of institutions have an interest rate between the bounds of the confidence interval. B. With 95% confidence, it can be said that the population mean interest rate is between the bounds of the confidence interval. C. If a large sample of institutions are taken approximately 95% of them will have an interest rate between the bounds of the confidence interval. D. Neither distribution can be used to construct the confidence interval.
