Find the mean and standard deviation of the DRIVE variable by using (A2:A36) and (A2:A36).  Assuming that this variable is normally distributed, what percentage of data would you predict would be less than 40 miles?  This would be based on the calculated probability.  Use the formula .DIST(40, mean, stdev,TRUE).  Now determine the percentage of data […]
