An Izod impact test was performed on 20 specimens of PVC pipe. The obtained standard deviation was s = 0.328. Assume that the random sample was drawn form a normal population N (µ, σ^2 ), with unknown mean value µ and unknown variance σ^2 . a) Give a 99% confidence interval for the variance σ^2 . b) Give a 99% upper confidence bound for the variance σ^2 . c) Test the hypothesis H0 : σ^2 = 0.1, against the two-sided...

In 2001, the mean household expenditure for energy was $1493, according to data obtained from the U.S. Energy Information Administration. An economist wanted to know whether this amount has changed significantly from its 2001 level. In a random sample of 35 households, he found the sample mean to be $1618 and the sample standard deviation to be $321. Test the claim that the mean expenditure has changed siginificanlty from the 2001 level at the 0.05 level of significance. State your...
