a. Compute the mean and standard deviation for this data set.
b. Delete the observation of 105.0 and recompute the mean and standard deviation. How do these values compare to the values from Part (a)? What does this suggest about using the mean and standard deviation as measures of center and spread for a data set with outliers?
