A data set consisting of the number of hours each of 40 students watched television over the weekend has a minimum value of 3 hours, a Q1 value of 5 hours, a median value of 6 hours, a Q3 value of 9 hours, and a maximum value of 12 hours. Draw a box plot representing this data distribution.

What is the interquartile range (IQR) for this distribution? What percent of the students fall within this interval?

Do you think the data distribution represented by the box plot is a skewed distribution? Why or why not?

Estimate the typical number of hours students watched television. Explain why you chose this value.
