At the U.S. Open Tennis Championship a statistician keeps track of every serve that a player hits during the tournament.  The statistician reported that the mean serve speed of a particular player was 100 miles per hour (mph) and the standard deviation of the serve speeds was 15 mph. Using the z-score approach for detecting outliers, which of the following serve speeds would represent outliers in the distribution of the player's serve speeds?

Speeds:  50 mph, 80 mph, and 105 mph
◦ 50 and 80 are both outliers, 105 is not.
◦ 50 is the only outlier.
◦ 50, 80, and 105 are all outliers.
◦ None of the three speeds are outliers.
