Question
For a simple random sample of pulse rates of women (measured in beats per minute), n = 139 and s= 13.2. 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 o in this case? Assume that the simple random sample is selected
from a normally distributed population.
