Hugger Polls contends that an agent conducts 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: 53, 57,
50, 55, 58, 54, 60, 52, 59, 62, 60, 60, 51, 59, and 56.
At the .05 level of significance, what do you conclude
about the number of in-depth surveys completed during a
week using the new form?
The solution uses hypothesis testing to analyze the survey conducted by Hugger.
