The following data are the distances between a sample of 20 retail stores and a large distribution center. The distances are in miles.
29; 30; 37; 40; 58; 67; 68; 69; 76; 81; 84; 95; 96; 96; 99; 106; 112; 127; 145; 150
How do I find the value that is one standard deviation below the mean? (I have to round my answer to one decimal place).

Add them up and get the mean and the sd using 1-var stats from STAT CALC 1
83.25 is mean
35.11 is sd for a sample (divide by n-1).
1 sd below is 48.14 or 48.1
