The file P09_33.xlsx contains real estate taxes paid by a sample of 170 homeowners in a Florida city.
a. Create a histogram of the taxes paid. Is there any visual evidence that the distribution of taxes paid is not normal?
b. Test the taxes paid for normality using the chisquare test. Is there enough evidence at the 5% significance level to conclude that taxes paid 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 taxes paid. Do these suggest the same conclusion as in part b? Explain.
