Test the claim about two population variances at the indicated level of significance alpha. Inte
Question: #2) Test the claim about two population variances at the indicated level of significance alpha. Interpret the results in the context of the claim.
A steel pipe fittings company claims the yield strength of its non-tempered couplings is more variable than that of its tempered couplings. A random sample of nine tempered couplings has a standard deviation of 13.1 megapascals, and a similar sample of nine non-tempered couplings has a standard deviation of 25.4 megapascals. From past data, it is known that the company's production process results in normally distributed yield strengths. Test the company's claim at alpha = 0.01.
