· A marketing research firm has put together a health survey that it would like to administer to individuals in malls across the state. They need to estimate the mean time it takes to complete the survey so that recruiters can give potential participants an idea of their time commitments. The survey is administered to a random sample of 40 individuals. The mean time to complete the survey is 14.6 minutes with a standard deviation of 2.8 minutes. Estimate the mean time to complete the survey using a 95% confidence interval.

The consumer group has reason to believe that the mean monthly mileage of cars rented in the U.S. this year is different from last year's mean, which was 2750 miles. The group plans to do a statistical test regarding the value of u. It chooses a random sample of monthly mileages and computes the mean of the sample to be 2900miles and the standard deviation to be 800 miles. Based on this information, answer the questions below. What are the null hypothesis (H,) and the alternative hypothesis (H,) that should be used for the test? Ho H is? u is ? In the context of this test, what is a Type II error? A Type II error is ? the hypothesis that u is ? when, in fact, u is ? Suppose that the group decides to reject the null hypothesis. What sort of error might it be…
