An insurance company offers four different deductible levels—none, low, medium, and high—for its homeowner's policyholders and three different levels—low, medium, and high—for its automobile policyholders. The accompanying table gives proportions for the various categories of policyholders who have both types of insurance. For example, the proportion of individuals with both low homeowner's deductible and low auto deductible is 0.07 (7% of all such individuals).

A marketing manager for a large cafeteria chain wished to investigate sales of coffee (i.e., sales is the variable she is trying to understand). Fourteen cafeterias that were similar in such respects as volume of business, type of clientele, and location were chosen for data collection. Data were collected on sales of coffee (in hundreds of gallons) and the number of coffee dispensers within the cafeteria. The results are shown below. Sales Number of Dispensers 631.9 1 628 1 692.5 2 688.4 2 747.4 3 773.3 3 791.4 4 803.4 4 838.7 5 879.6 5 881 6 841.1 6 860.6 7 883.8 7 Create a scatter plot and then fit a quadratic model to predict sales from the number of dispensers. If we define y to be sales (in hundreds of gallons) and x to be the number of dispensers, what is the correct quadratic model?

The Dow Jones Industrial Average (DJIA) and the Standard & Poors 500 (S&P500) indexes are used as measures of overall movement in the stock market. The DJIA is based on the price movements of 30 large companies; the S&P 500 is an index composed of 500 stocks. Some say the S&P is a better measure of stock market performance because it is broader based. The closing prices for the DJIA and S&P500 for 20 weeks starting on 9/9/2005 are included in cells E1 to G21. The DJIA data is in cells F1 to F21 and the data for S&P 500 is in cells G1 to G21. Both data sets have labels in first row. Develop the estimated regression equation using DJIA as the independent variable. Place output in cell H1 Is the relationship between DJIA and S&P500 significant using alpha .05? Did the estimated regression equation provide a good fit? (explain) Suppose that the closing price for DJIA is 11,000. Estimate the closing price for the S&P500 Date…
A veterinarian wishes to compare the number of times race horses are reported to be lame during a 12-month period, compared with similar horses that are not raced. The veterinarian is particularly interested whether the exercise schedule used in racing may contribute to lameness rather than the total amount of exercise. The veterinarian chooses 9 race horses and then selects a matching horse that is instead used for jumping, matching horses based on age, breed, and exercising a similar number of hours each week. The table below contains the observed number of times a horse was reported as lame. Group 1 Race Jump 7 2 O (-1.329, 2.663) O (-3.405, 4.738) O (-2.459, 3.792) 2 O (-1.590, 2.923) 8 1 3 2 3 4 0 2 5 3 4 Horse 6 1 1 7 st 4 3 8 2 7 A 90% confidence interval for the MEAN DIFFERENCE in the number of times a horse is lame is given by: (hint: remember this is a matched pairs data set) 9 6 4
