Unformatted text preview: b. The rejection region is of the form Z c for some c . Hence the Pvalue is P ( X 1 . 42) where X is a standard normal distribution. Thus Pvalue equals 1(1 . 42) = 0 . 0778. Since this is larger than 0 . 05, the null hypothesis is not rejected at 5% level. c. The rejection region is of the form  Z  c for some c . Hence the Pvalue is P (  X  1 . 42) where X is a standard normal distribution. Thus Pvalue equals 2(1(1 . 42)) = 0 . 1556. Since this is larger than 0 . 05, the null hypothesis is not rejected at 5% level. 1...
