A simple random sample of 45 men from a normally distributed population results in a standard deviation of 10.4 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. Compute the test statistic. (Round to three decimal places as needed.) b. Find the P-value. P-value = (Round to four decimal places as needed.) c. State the conclusion. V evidence to Ho, because the P-value is the level of significance. There is warrant rejection of the claim that the standard deviation of men's pulse rates is equal to 10 beats per minute.
