Bags of a certain brand of tortilla chips claim to have a net weight of 14 oz. net weights actually vary slightly from bag to bag. assume net weights are normally distributed. a representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is less than advertised and so intends to test the hypotheses h0: \mu = 14, ha: \mu < 14. to do this, he selects 16 bags of tortilla chips of this brand at random and determines the net weight of each. he finds a sample mean of 13.88 oz with a standard deviation of s = 0.24 oz. assume the standard deviation for the distribution of actual net weights for bags of tortilla chips of this brand is \sigma = 0.25. at the 5% significance level, what is the power of our test when, in fact, \mu = 13.8 oz?
