Question
For a simple random sample of pulse rates of women​ (measured in beats per​ minute),
n=144
and
s=13.9.
The normal range of pulse rates of adults is typically given as
60
to
100
beats per minute. If the range rule of thumb is applied to that normal​ range, the result is a standard deviation of
10
beats per minute. Use the sample results with a
0.01
significance level to test the claim that pulse rates of women have a standard deviation equal to
10
beats per​ minute; see the accompanying JMP display that results from using the original list of pulse rates instead of the summary statistics.​ (Hint: The bottom three rows of the display provide​ P-values for a​ two-tailed test, a​ left-tailed test, and a​ right-tailed test,
respectively.​)
What do the results indicate about the effectiveness of using the range rule of thumb with the​ "normal range" from
60
to
100
beats per minute for estimating
σ
in this​ case?
Assume
that the simple random sample is selected from a normally distributed population.
