Consider the following sample data.
| Sample A: | 14, 16, 18 | 
| Sample B: | 72, 74, 76 | 
| Sample C: | 1,055; 1,057; 1,059 | 
(a) Find the mean and standard deviation for each
sample.
| Sample A: | Sample B: | Sample C: | |
| Mean | |||
| Sample Standard Deviation | |||
(b) What does this exercise show about the
standard deviation?
The idea is to illustrate that the standard deviation is not a function of the value of the mean.
