8.4-3. Let X equal the weight (in grams) of a Hershey's grape-flavored Jolly Rancher. Denote the median of X by m. We shall test Ho: m = 5.900 against H1: m > 5.900. A random sample of size n = 25 yielded the following ordered data: 5.625 5.665 5.697 5.837 5.863 5.870 5.878 5.884 5.908 5.967 6.019 6.020 6.029 6.032 6.037 6.045 6.049 6.050 6.079 6.116 6.159 6.186 6.199 6.307 6.387 (a) Use the sign test to test the hypothesis. (b) Use the Wilcoxon test statistic to test the hypothesis. (c) Use a f test to test the hypothesis. (d) Write a short comparison of the three tests
