Question: Suppose a sample of national test-takers spent an average 179 minutes with a standard deviation of 12 minutes to take the exam.
- What is the null and alternative hypothesis to determine if the population average test taker takes fewer than 185 minutes?
- Calculate the appropriate test statistic.
- Using a level of significance of 1%, what is the critical value?
- Do you reject the null hypothesis?
- What do know about the average time for taking the test in the population?
