Question Help A simple random sample of 49 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 0.10 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 alternative hypotheses. Choose the correct answer below. O A. Ho: o2 10 beats per minute H:0<10 beats per minute B. Ho: o = 10 beats per minute H1:0+ 10 beats per minute O C. Ho: o + 10 beats per minute H7: 0 = 10 beats per minute O D. Ho: o= 10 beats per minute H1: o< 10 beats per minute %3D GUS b. Compute the test statistic. X = 66.835 (Round to three decimal places as needed.) c. Find the P-value. P-value = (Round to four decimal places as needed.) d. State the conclusion. sufficient evidence to warrant rejection of the claim that the standard deviation of men's pulse rates is equal to Reject Ho, because the P-value is less than or equal to the level of significance.

A simple random sample of 49 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 0.10 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 alternative hypotheses. Choose the correct answer below.
O A. Ho: o2 10 beats per minute
H:0<10 beats per minute
B. Ho: o = 10 beats per minute
H1:0+ 10 beats per minute
O C. Ho: o + 10 beats per minute
H7: 0 = 10 beats per minute
O D. Ho: o= 10 beats per minute
