It is of interest to determine if a branch of a Japanese food business conforms to the standard90 gram serving of pork katsu. It might irritate customers if the serving was below 90 grams, and the business might fail to meet target earnings if above 90 grams. Following are weights (in grams) of a random sample of eight katsu servings from this branch: 86.1 87.6 88.8 88.8 89.5 90 90.6 90.6 At 0.10 level of significance, test the hypothesis that the population mean weight of the katsu servings from the branch conforms to the standard 90 grams. Assume that the weights are normally distributed. What is the alternative hypothesis? Ha: M =/= 90 O Ha: M > 90 O Ha: M < 90 O Ha: M = 90
