A beverage company has two bottling plants in different parts of the world. To insure uniformity in their product, the variances of the weights of the bottles at the two plants should be equal. But John, the company's vice president of quality assurance, suspects that the variance at bottling plant A is less than the variance at bottling plant B. To test his suspicions, John samples 33 bottles from bottling plant A and 35 bottles from bottling plant B, with the following results (in ounces): Bottling Plant A: 12.9, 14.2, 13.7, 13.2, 13.8, 12.6, 14.5, 14.2, 13.3, 14.2, 13.4, 13.1, 13.1, 13.1, 13.9, 14, 13.4, 12.8, 13.7, 12.8, 12.8, 13.6, 12.8, 13.1, 13.3, 12.2, 12.6, 12.4, 12.7, 13.6, 13, 13.1, 13.4 Bottling Plant B: 13.3, 13.7, 13.4, 13.5, 12.6, 12.6, 13, 14.4, 13.1, 13.1, 13.4, 13.7, 12.6, 13.7, 13, 12.5, 12.7, 13.4 13.8, 12.8, 12.8, 12.9, 13.6, 13.2, 13.2, 14, 13.2, 13.1, 14.3, 13.6, 13.4, 13.2, 13, 13.1, 12.8 Perform a hypothesis test using a 8% evel of significance to test John's suspicions.
