(a) Determine the sample standard deviation weight
s= gram
(Round to two decimal places as needed.)
(b) On the basis of the histogram on the right, comment on the appropriateness of using the empirical rule to make any general statements about the weights of the candies
The histogram is bell-shaped so the empirical rule can be used.
The histogram is not bell-shaped so the empirical rule cannot be used.
(c) Use the Empirical Rule to determine the percentage of candies with weights between 0.72 and 0.96 gram
Hint x=0.84.

If the true incident rate of Kaposi’s sarcoma in the United States is 6 cases/million/year based on a nationwide surveillance in 2014. Test whether the rate of Kaposi’s sarcoma in Tanzania is different from the United States at the 0.05 significance level. Be sure to state the null and alternative hypothesis. Carry out the appropriate hypothesis test by hand (you can also use SAS) and report the test statistic and the p-value and your conclusion in the context of the problem.
