The chief loan officer of La Crosse Home Mortgage Company summarized the housing loans extended by the company in 2010 according to type and term of the loan. Her list shows that 65% of the loans were fixed-rate mortgages (F), 26% were adjustable-rate mortgages (A), and 9% belong to some other category (0) (mostly second trust-deed loans and loans extended under the graduated payment plan). Of the fixed-rate mortgages, 41% were 30-year loans, and 59% were 15-year loans; of the adjustable-rate mortgages, 28% were 30-year loans and 72% were 15-year loans; finally, of the other loans, extended, 30% were 20-year loans, 64% were 10-year loans, and 6% were for a term of 5 years or less. (a) Draw a tree diagram representing these data. 20 <=5 15 30 15 30 15 30 15 30 10 20 <=5 10 20 = 5 10 20 <=5 15 30 15 30 10 20 <=5 15 30 (b) What is the probability that a home loan extended by La Crosse has an adjustable rate and is for a term of 15 years?

3. An investment broker wants to invest up to $20,000. She can purchase type A bond yielding a 10% return and she can purchase a riskier type B bond yielding a 15% return. She wants to invest at least as much in the type A bond as in the type B bond to reduce her risk.

11. Irwin's sells a particular model of fan, with most of the sales being made in the summer months. Irwin's makes a one-time purchase of the fans prior to each summer season at a cost of $40 each and sells each fan for $60. Any fans unsold at the end of the summer season are marked down to $29 and sold in a special fall sale. Virtually all marked-down fans are sold. The following is the number of sales of fans during the past 10 summers: 30, 50, 30, 60, 10, 40, 30, 30, 20, 40. a. Estimate the mean and the variance of the demand for fans each summer. b. Assume that the demand for fans each summer follows a normal distribution, with mean and variance given by what you obtained in part (a). Determine the optimal number of fans for Irwin's to buy prior to each summer season. c. Based on the observed 10 values of the prior demand, construct an empirical probability distribution of summer demand and determine the optimal number of fans for Irwin's to buy based on the empirical distribution.…
