Question

The file P02_11.xlsx contains data on 148 houses sold in a certain suburban region.
a. Create a histogram of the selling prices. Is there any visual evidence that the distribution of selling prices is not normal?
b. Test the selling prices for normality using the chi-square test. Is there enough evidence at the 5% significance level to conclude that selling prices are not normally distributed? If so, what is there about the distribution that is not normal?
c. Use the Lilliefors test and the Q-Q plot to check for normality of selling prices. Do these suggest the same conclusion as in part b? Explain.
