Park officials make predictions of times to the next eruption of
a particular​ geyser, and collect data for the
errors​ (minutes) in those predictions. The display from
technology available below results from using the prediction errors
to test the claim that the mean prediction error is equal to zero.
Comment on the accuracy of the predictions. Use a
0.05
significance level. Identify the null and
alternative​ hypotheses, test​ statistic, P-value, and
state the final conclusion that addresses the original claim.
