#30 Guarantee: Watches Accrotime is a manufacturer of quartz crystal watches. Accrotimeresearches haves shown that the watches they make have an average life of 28 months beforecertain electronic components deteriorate, causing the watch to become unreliable. The standarddeviation of watch lifetimes is 5 months, and the distribution of lifetimes is normal.(a) To offer a full refund guarantee on any defective watch for 2 years after purchase, whatpercentage of total production should the company expect to replace?(b) If Accrotinme does not want to make refunds on more than 12% of the watches it makes,how long should the guarantee period be ( to the nearest month)?

Given data Mean (µ) = 28 Standard deviation (σ) = 5 2 years = 24 months

Suppose that the borrowing rate that your client faces is 9%. Assume that the equity market index has an expected return of 13% and standard deviation of 25%, that rf = 5%. Your fund manages a risky portfolio, with the following details: E(rp) = 11%, p = 15%. What is the largest percentage fee that a client currently lending (y 1)? (Negative values should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 1 decimal place.) y 1
Andrew plans to retire in 40 years. He plans to invest part of his retirement funds in stocks, so he seeks out information on past returns. He learns that over the entire 20th century, the real (that is, adjusted for inflation) annual returns on U.S. common stocks had mean 8.7% and standard deviation 20.2%. The distribution of annual returns on common stocks is roughly symmetric, so the mean return over even a moderate number of years is close to Normal. What is the probability (assuming that past pattern of variation continues) that the mean annual return on common stocks over the next 40 years will exceed 10%? What is the probability that the mean return will be less than 5%?
