Assume a significance level of

alpha equals 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

69

bpm. The hypothesis test results in a P-value of

0.0938

.

a. State a conclusion about the null hypothesis. (Reject

Upper H 0

or fail to reject

Upper H 0

.)

Choose the correct answer below.

A.

Fail to reject

Upper H 0

because the P-value is

less than or equal to

alpha

.

B.

Reject

Upper H 0

because the P-value is

greater than

alpha

.

C.

Fail to reject

Upper H 0

because the P-value is

greater than

alpha

.

D.

Reject

Upper H 0

because the P-value is

less than or equal to

alpha

.

b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion?

A.

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

69

bpm.

B.

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

69

bpm.

C.

The mean pulse rate (in beats per minute) of the group of adult males is not

69

bpm.

D.

The mean pulse rate (in beats per minute) of the group of adult males is

69

bpm.
