Claim: The standard deviation at pulse rates at adult males is more than 10 bpm. For a random sample of 145 adult males, the pulse rates have a standard deviation M105 bpm. Find the value of the test statistic. The value of the test statistic is . (Round to two decimal places as needed.) The test statistic of z = 2.24 is obtained when testing the claim that p > 0.8. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.10, should we reject Ho or should we fail to reject Ho?

P-value = (Round to three decimal places as needed.) c. Choose the correct conclusion below. O A. Fail to reject Ho. There is not sufficient evidence to support the claim that p > 0.8. O B. Reject Ho. There is sufficient evidence to support the claim that p > 0.8. O C. Reject Ho. There is not sufficient evidence to support the claim that p > 0.8. O D. Fail to reject Ho. There is sufficient evidence to support the claim that p > 0.8.The test statistic of z = - 2.41 is obtained when testing the claim that p
