3. The amount of time (in minutes) it took each individual in asample of athletes to run a mile was recorded. In thisparticular sample, most of the athletes were able to run themile quickly, but there were a small number of athletes whowere not fast runners and needed more time to complete themile. Two measures of center were computed for thissample: 12.9 minutes and 9.5 minutes. One of thesemeasures is the mean and one is the median. Whichmeasure must be the mean?A. The mean is 9.5 minutes because the distribution ofrunning times would be skewed to the left.B. The mean is 9.5 minutes because the distribution ofrunning times would be skewed to the right.c. The mean is 12.9 minutes because the distribution ofrunning times would be skewed to the left.D. The mean is 12.9 minutes because the distributionrunning times would be skewed to the right.
