An appliance manufacturer claims to have developed a compact microwave oven that consumes a mean of no more than 250 w. from previous studies, it is believed that power consumption for microwave ovens is normally distributed with a population standard deviation of 15 w. a consumer group has decided to try to discover if the claim appears true. they take a sample of 20 microwave ovens and find that they consume a mean of 257.3 w. what is the critical value with a level of significance of 0.05 and what is the test statistic and what is the p value?

Prove (a) cosh2(x) β sinh2(x) = 1 and (b) 1 β tanh 2(x) = sech 2(x). solution (a) cosh2(x) β sinh2(x) = ex + eβx 2 2 β 2 = e2x + 2 + eβ2x 4 β = 4 = . (b) we start with the identity proved in part (a): cosh2(x) β sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 β sinh2(x) cosh2(x) = 1 or 1 β tanh 2(x) = .
