Question

One of the quality measures in testing is the consistency of the results. The consistency is measured by computing the variance of the results in repeated testing. Two types of blood glucose meter testing kits were tested. Blood from the one vial was used for the testing. Suppose 16 Brand X kits yielded a variance of 2.19 while 25 Brand Y kits yielded a variance of 2.30, test the claim that the two testing kits have different variances.

a.What is the degrees of freedom for the numerator?

b.What is the degrees of freedom for the denominator?

c.What is the test statistic? Use 2 decimal places.
