▾ Part 1 of 4 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 Parvez, 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, Parvez samples 34 bottles from bottling plant A and 34 bottles from bottling plant B, with the following results (in ounces): Bottling Plant A: 12.4, 12.5, 12, 13.3, 11.6, 11.9, 12.7, 13.1, 14.1, 12.4, 12, 12.4, 12.9, 12.2, 12.6, 12.7, 12.3, 12.5, 12.7, 12.7, 12.8, 12.8, 13.6, 11.4, 12.4, 12.5, 13.1, 12.6, 13.1, 12.6, 12.2, 12.9, 12.7, 13.5 Bottling Plant B: 12.1, 12.3, 12.2, 12.2, 12.4, 12.2, 12.2, 12.5, 12.4, 13.1, 12.2, 12.6, 12.1, 11.9, 13.2, 11.2, 12.9, 13.1, 11.6, 13.5, 12, 12.3, 12.4, 13, 12.9, 12.9, 12.4, 13.2, 12.5, 12.9, 13, 13.1, 12.3, 11.6 Perform a hypothesis test using a 7% level of significance to test Parvez's suspicions.
