Question: 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 is:
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?
