A manufacturer of paper products wants to compare the variation in daily production levels at two paper mills. Independent random samples of days are selected from each mill, and the production levels (in units) are recorded. The data are shown in Table 8.8. Do these data provide sufficient evidence to indicate a difference in the variability of production levels at the two paper mills? (Use α = .10.)
