7.    A recent national survey found that high school students watched an average (mean) of
6.8 DVDs per month with a population standard deviation of 0.5 hours. The distribution of
Â
Â
Â
times follows the normal distribution. A random sample of 36 college students revealed that the mean number of DVDs watched last month was 6.2. At the .05 significance level, can we conclude that college students watch fewer DVDs a month than high school  students?
