Question: Data File ERWAITING contains the waiting times in minutes for 15 randomly selected patients at a hospital main emergency room facility and at three satellite facilities.

1. At the .05 level of significance, is there evidence that the mean waiting time at the main facility is more than one hour?

   Complete the following:
   State H 0 .
   2. State H 1 .
   3. State the value of α.
   4. State the value of the test statistic.
   5. State the p-value.
   6. State the decision in terms of H 0 and why.
   7. State the decision in terms of the problem.

2. Suppose you use a .01 level of significance instead of a .05 level. Without doing the problem again, would the result be different from that in part (a)? Explain your answer.
