Extracted text: A simple random sample of 50 men from a nomally distributed population results in a standard deviation of 9.8 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 0.10 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. a. Identify the null and altemative hypotheses. Choose the corect answer below. B.
