Question
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.
