Question: Revenue for a full-service funeral. According to the National Funeral Directors Association (NFDA), the nation's 22,000 funeral homes collected an average of $6,500 per full-service funeral in 2005 (NFDA Fact Sheet, 2009). A random sample of 36 funeral homes reported revenue data for 2009 . Among other measures, each reported its average fee for a full-service funeral. These data (in thousands of dollars) are shown in the following table and saved in the FUNERAL file.

1. What are the appropriate null and alternative hypotheses to test whether the average full-service fee of U.S. funeral homes in 2009 exceeds $6.500?
2. Conduct the test at \(\alpha=.05\). Do the sample data provide sufficient evidence to conclude that the average fee in 2009 was higher than in 2005?
3. In conducting the test, was it necessary to assume that the population of average full-service fees was normally distributed? Justify your answer.
