Question
A simple random sample of
46
men from a normally distributed population results in a standard deviation of
7.7
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. Complete parts​ (a) through​ (d) below.
