Question: Consider the computer output shown below.

1. Fill in the missing values in the output. Can the null hypothesis be rejected at the 0.05 level? Why?
2. Is this a one-sided or a two-sided test?
3. If the hypotheses had been \(H_{0}: \mu=90\) versus \(H_{1}: \mu \neq 90\) would you reject the null hypothesis at the 0.05 level?
4. Use the output and the \(t\) table to find a 99 percent two-sided CI on the mean.
5. What is the \(P\) -value if the alternative hypothesis is \(H_{1}: \mu>91\) ?
