Fifty-four wild bears were anesthetized, and their weights and chest sizes were measured. Results are showing in the graph below. IS there sufficient evidence to support the claim that there is a linear correlation between weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that a measured chest size can be used to predict the weight?

Income and housing revisited In Chapter 6, Exercise 32, we learned that the Office of Federal Housing Enter-prise Oversight (OFHEO) collects data on various as-pects of housing costs around the United States. Here’s a scatterplot (by state) of the Housing Cost Index (HCI)versus the Median Family Income (MFI) for the 50 states.The correlation is r = 0.65. The mean HCI is 338.2,with a standard deviation of 116.55. The mean MFI is$46,234, with a standard deviation of $7072.47.a) Is a regression analysis appropriate? Explain.b) What is the equation that predicts Housing Cost Indexfrom median family income?c) For a state with MFI = +44,993, what would be thepredicted HCI?d) Washington, DC, has an MFI of $44,993 and an HCIof 548.02.
