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

Assume that the weights are normally distributed.
