# Value of test statistic

A recent national survey found that high school students watched an average (mean) of 6.8 videos per month. A random sample of 36 college students revealed that the mean number of videos watched last month was 6.2, with a standard deviation of 0.5. At the .05 significance level, can we conclude that college students watch fewer videos a month than high school students? (a) State the null and alternate hypotheses. (b) State your decision rule. (c) Compute the value of the test statistic. (d) what is your decision regarding the null hypothesis?
