A high school teacher at a small private school assigns trigonometry practice problems to be worked via the net. Students must use a password to access the problems and the time of log-in and log-off are automatically recorded for the teacher. At the end of the week, the teacher examines the amount of time each student spent working the assigned problems. The data provided in minutes are: 15, 28, 25, 48, 22, 43, 49, 34, 22, 33, 27, 25, 22, 20, and 39.

a.) Find the Mean, Median, and Mode for the above data.

b.) What does this information tell you about students' length of time on the computer solving trigonometry problems?

c.) Is this data skewed? Why?
