Do WCC student spend lots of time playing video games? According to a recent study published by the American Statistics for Educators Journal, statistics students spend, on average, 80 minutes a week playing video games. A certain instructor of statistics at WCC believes that students in his class spend less than this amount of time playing video games per week. To test his belief, he randomly samples 25 students and finds the sample mean to be 74 minutes with a standard deviation of 9 minutes. Test the instructors claim at an α = 0.05 level of significance.

Use the same sample data to construct a 95% confidence interval for the mean hours of video game playing for WCC students. Does this interval support your conclusion? Why, or why not?
