A pharmaceutical company is about to launch a new manufacturing process in addition to the existing one. The quality control manager believes that the new method results in a different variation in the weights of the capsules. To verify the claim, the samples from each production line were obtained and the results are below (in mg): Production Line 1: 98.9 100.7 104.7 101.9 101.6 101 101 98.8 99.4 100.3 (Note: The average and the standard deviation of the data are respectively 100.83 mg and 1.731 mg.) Production Line 2: 100.4 102 97.6 99.9 100 102.5 100.4 98.6 97.5 99.1 100.8 99.3 99.5 101.6 99.1 99 98.6 (Note: The average and the standard deviation of the data are respectively 99.76 mg and 1.416 mg.) Use a 1% significance level to test the claim that the standard deviation of the capsule weights in the production line 1 is greater than the standard deviation of the capsule weights in the production line 2. If normality plots are not provided assume that the samples are from normal populations.
