Shipments of meat, meat by-products, and other ingredients are mixed together in several filling lines at a pet food canning factory. Operations managers suspect that, although the mean amount filled per can of pet food is usually stable, the variability of the cans filled in line A is greater than that of line B. The following data from a sample of 8-ounce cans is as follows:

a. At the 0.05 level of significance, is there evidence that the variance in line A is greater than the variance in line B?
b. Interpret the p-value.
c. What assumption do you need to make in (a) about the two populations in order to justify your use of the F test?
