(a) Fill in the missing values in the output. Can the null hypothesis be rejected at the 0.05 level? Why?

(b) Is this a one-sided or a two-sided test?

(c) If the hypotheses had been H0 : $ $ 90 versus H1 : $ ! 90 would you reject the null hypothesis at the 0.05 level?

(d) Use the output and the t table to find a 99 percent twosided CI on the mean.

(e) What is the P-value if the alternative hypothesis is H1 : $ , 91?
