#### Solution Preview

The mean is the average. Add all the values and divide by the number of values.

Mean = (5.25 + 5.95 + 10.00 + 5.45 + 5.30 + 6.85 + 9.30 + 8.20 + 6.20 + 7.10)/10

Mean = 6.96

Standard deviation is a measure of variability within the range of values.

SD = ...

#### Solution Summary

This solution shows how to do a calculation of mean, standard deviation, standard error, and range for a given set of white blood cell counts.
