SOLUTION: A simple random sample of 44 men from a normally distributed population results in a standard deviation of 11.8 beats per minute. The normal range of pulse rates of adults is typic

Question 1081162: A simple random sample of 44 men from a normally distributed population results in a standard deviation of 11.8 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.

The ratio of the squared sd s is 11.8^2/100=1.3924.
This is an F(1,oo) test with the value 1.3924 and the p-value 0.099 or 0.1
These sd s may be considered equal, since Ho is not rejected.
