A simple random sample of 32 men from a normally
distributed population results in a standard deviation of
8.7 beats per minute. 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
0.05 significance level to test the claim that pulse rates
of men have a standard deviation equal to 10 beats per
minute.
test statistics X^2 = 23.464
