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 103 miles per hour (mph) and the standard deviation of the serve speeds was 12 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: 61 mph, 115 mph, and 127 mph

◦ 61, 115, and 127 are all outliers.
◦ None of the three speeds is an outlier.
◦ 61 and 115 are both outliers, but 127 is not.
