The North Valley Real Estate data report information on the homes sold last year.

a. At the .02 significance level, is there a difference in the variability of the selling prices of the homes that have a pool versus those that do not have a pool?

b. At the .02 significance level, is there a difference in the variability of the selling prices of the homes with an attached garage versus those that do not have an attached garage?

d. Adam Marty recently joined North Valley Real Estate and was assigned 20 homes to market and show. When he was hired, North Valley assured him that the 20 homes would be fairly assigned to him. When he reviewed the selling prices of his assigned homes, he thought that the prices were much below the average of $357,000. Adam was able to find the data of the homes assigned to agents in the firm. Use statistical inference to compare the mean price of homes assigned to him to the mean price of homes assigned to the other agents. What do the results indicate? How is your analysis defining fairness?

e. Home buyers finance the purchase of their home with a mortgage. In these data, the mortgages are either a fixed rate mortgage paid over 30 years or an adjustable rate mortgage. The adjustable rate mortgage provides a lower introductory interest rate for the first 5 years of occupancy. Then, in the fifth year, the rate is adjusted to the current rate plus an additional percent. Usually, the adjusted rate is higher than the “introductory” rate. With this information, we may predict that the average years of occupancy would be different for home owners based on the type of mortgage and whether they defaulted on the mortgage. Use the data to evaluate this prediction.
