Hugger Polls contends that an agent conducts a mean of 53 in-depth home surveys every week. A streamlined survey form has been introduced, and Hugger wants to evaluate its effectiveness. The number of in-depth surveys conducted during a week by a random sample of agents are: <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:o ffice" /?>
53 57 50 55 58 54 60 52 59 62 60 60 51 59 56
At the .05 level of significance, can we conclude that the mean number of interviews conducted by the agents is more than 53 per week?
(a) What is the decision rule? (Round your answer to 3 decimal places.)
Reject H0 : ? ? 53 and accept H1 : ? > 53 when the test statistic is greater than
(b) The value of the test statistic is . (Round your answer to 2 decimal places.)
