8. The Muscat Distributing Company is investigating two different scheduling methods for its truck drivers. The following sample data give the number of delivery miles each driver drove per day for the two methods. Method A 14 19 11 10 11 Method B 5 26 13 14 7 10 a Compute the mean and the standard deviation for each of the two methods. b. Compute the coefficient of variation for each method and discuss which method seems to provide the least relative variability in the distance travelled.
