A regulation baseball should weigh 145 grams. A company produces baseballs for the MLB. To help ensure a high degree of accuracy, a random sample of 24 baseballs is drawn from the production line every 45 minutes and each baseball is measured for accuracy. If the average weight of the sample is found to be significantly different than 145 grams, then the production line is shut down for inspection. The mean weight of a recent sample of 24 baseballs was found to be 154.08 grams. Use the p-value method to test the hypothesis that the mean weight of a baseball produced by this company is different than 145 grams, using a = 0.025. Assume that the distribution of weights of all baseballs produced by this company is known to be approximately normally distributed with a standard deviation of 16.8 grams. State the null and alternative hypothesis for this test. Ho: ? v H1: ? v
