(a) How many degrees of freedom are there on the -test statistic?
(b) Fill in the missing values. You may calculate bounds on the -value. What conclusions would you draw?
(c) Is this a one-sided or a two-sided test?
(d) Construct a two-sided
on the mean.
(e) If the hypothesis had been \(H_0:\ \mu=12\) versus \(H_1:\ \mu>12\), would your conclusions change?
(f) If the hypothesis had been \(H_0:\ \mu=11.5\), versus \(H_1:\ \mu\ne11.5\), would your conclusions change? Answer this question by using the CI computed in part (d).
