Question

Assume a significance level of

alpha equals 0.05?=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

7373

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

0.00920.0092.

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

Upper H 0H0

or fail to reject

Upper H 0H0?.)

Choose the correct answer below.

A.

Fail to rejectFail to reject

Upper H 0H0

because the? P-value is

greater thangreater than

alpha?.

B.

RejectReject

Upper H 0H0

because the? P-value is

greater thangreater than

alpha?.

C.

RejectReject

Upper H 0H0

because the? P-value is

less than or equal toless than or equal to

alpha?.

D.

Fail to rejectFail to reject

Upper H 0H0

because the? P-value is

less than or equal toless 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 notis 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

7373

bpm.

B.

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

7373

bpm.

C.

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

7373

bpm.

D.

There

isis

sufficient evidence to warrant rejection of the claim that the mean pulse rate? (in beats per? minute) of the group of adult males is

7373

bpm.
