Question: Consider the weight of paper data from Technometrics in Exercise 10-32. Is there evidence that the variance of the weight measurement differs for the sheets

Consider the weight of paper data from Technometrics in Exercise 10-32. Is there evidence that the variance of the weight measurement differs for the sheets of paper? Use Î± = 0.05. Explain how this test can be conducted with a confidence interval.

Exercise 10-32

An article in Technometrics (1999, Vol. 41, pp. 202€“211) studied the capability of a gauge by measuring the weights of two sheets of paper. The data follow.
