Claim: The standard deviation of pulse rates of adult males is less than 10 bpm. For a random sample of 152 adult males, the pulse rates have a standard deviation of 9.2 bom. Complete parts (a) and (b) below a Express the original claim in symbolic form, bpm (Type an integer or a decimal. Do not round)
Assume a significance level of a 0.1 and use the given information to complete parts (a) and (b) below Original claim: The mean pulse rate (in beats per minute) of a certain group of adult males is 74 bpm. The hypothesis test results in a P-value of 0.0056 a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Hg.) Choose the correct answer below A. Fail to reject Hy because the P-value is less than or equal to a B. Fail to reject Ho because the P-value is greater than a C. Reject H, because the P-value is less than or equal to a OD. Reject H, because the P-value is greater than a
