The printing time of a weekly magazine was studied using two different machines, and . Eight different magazines were randomly assigned to each of the two printing machines, and produced standard deviations = 2.08, and = 1.66 for machines and , respectively. Assume the required assumptions are met and use = 0.05 to determine if the variances for the two machines are different.
Test Statistic = ______________
Reject Region: Reject H₀ if F > ______________
Conclusion: ______________
There is ______________ to indicate a difference in the population variances.
