Question

The standard deviation of is 14.01 and the mean is 37.7

I have created a dot plot of the data and now I need to find out within how many standard deviations of the mean does all the data fall but I am not sure how to do this Please help

Answer 1

The maximum value is 70, which is
(70-37.7)/14.01=2.3 standard deviations above the mean.

You can calculate similarly for the smallest value of 15.
