A recent national survey found that high school students watched an average (mean) of 7.3 DVDs per month with a population standard deviation of 0.6 hours. The distribution of times follows the normal distribution. A random sample of 42 college students revealed that the mean number of DVDs watched last month was 6.7. At the 0.01 significance level, can we conclude that college students watch fewer DVDs a month than high school students? Use 0 = 0.01. a. State the null hypothesis and the alternate hypothesis. Ho: U X 7.3 HI: U 7.3 b. State the decision rule. Reject Ho if z 3-2.33 c. Compute the value of the test statistic. (Round the final answer to 1 decimal place.) Value of the test statistic 6.5 x d. What is your decision regarding Ho? Reject Ho. =. What is the p-value? The p-value is close to 0
