Question

Assume a significance level of α=0.05 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 70 bpm. The hypothesis test results in a P-value of 0.0076.

12. Assume a significance level of a = 0.05 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 70 bpm. The hypothesis test results in a P-value of 0.0076.
a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho.) Choose the correct answer below.
O A. Reject H, because the P-value is greater than a
O B.
Fail to reject Ho because the P-value is greater than α.
O C.
Fail to reject Ho because the P-value is less than or equal to a.
O D. Reject H because the P-value is less than or equal to α.
b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion?
O A. There is not sufficient evidence to warrant rejection of the claim that the mean pulse rate (in beats per minute) of the group of adult males is 70 bpm.
OB. There is sufficient evidence to warrant rejection of the claim that the mean pulse rate (in beats per minute) of the group of adult males is 70 bpm.
C. The mean pulse rate (in beats per minute) of the group of adult males is not 70 bpm.
D. The mean pulse rate (in beats per minute) of the group of adult males is 70 bpm.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
