The statistician reported that the mean serve speed of a particular player was 101 miles per hour (mph) and the standard deviation of the serve speeds was 13 mph.

2. 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 101 miles per hour (mph) and the standard
deviation of the serve speeds was 13 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: 56 mph, 114 mph, and 127 mph
None of the three speeds is an outlier.
56 and 114 are both outliers, but 127 is not.
56, 114, and 127 are all outliers.
56 is the only outlier.
