Example: Mean Height of a Population
Estimate the mean height of a population of women, given the random sample
below. Because heights among a biological population tend to be normally
distributed, a
t
distribution confidence interval can be used when estimating the
mean. The 10 height values below are the first 10 of 90 values, randomly generated
from a normally distributed population with an assumed mean of 65 inches and a
standard deviation of 2.5 inches.
This example uses an inferential statistics editor. An editor prompts you for test
information. See page 7 for another example of using an inferential statistics
editor. You can also enter test parameters without using an editor. See page 8 for
an example of bypassing the inferential statistics editors.
