A quality control analyst is verifying that the 1 lb bags of coffee are indeed 16 oz. He knows if it is different than 16 oz. he will have to shut down the machine and recalibrate it. His hypotheses are: Ho : 1 = 16oz. Ha: μ# 16oz. Each hour he selects 30 bags and calculates the average. His latest test statistic is 1.68, and his P-value is 0.093. Using a significance level of a = 5%, what is his conclusion? Reject Ho. u is different than 16 oz. O Fail to reject, Ho, you cant prove that u is not different than 16 oz. O Accept Ha. H is not different than 16 oz. Fail to reject, Ho, you cant prove that u is different than 16 oz.
