A basketball player practices free throws by taking 25 shots each day, and he records the number of shots missed each day in order to track his progress. The numbers of shots missed on days 1 through 30 are, respectively, 17, 15, 16, 18, 14, 15, 13, 12, 10, 11, 11, 10, 9, 10, 9, 9, 9, 10, 8, 10, 6, 8, 9, 8, 7, 9, 8, 7, 5, 8.

a. Construct a stem- and- leaf display and a time series plot of the numbers of missed shots.

b. Do you think that the stem- and- leaf display is representative of the numbers of shots that the player will miss on future days? Why or why not? DS
