Question

Assume a significance level of

alpha equals 0.1α=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

7575

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

0.08930.0893.

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.

RejectReject

Upper H 0H0

because the​ P-value is

greater thangreater than

alphaα.

B.

Fail to rejectFail to reject

Upper H 0H0

because the​ P-value is

greater thangreater than

alphaα.

C.

RejectReject

Upper H 0H0

because the​ P-value is

less than or equal toless than or equal to

alphaα.

D.

Fail to rejectFail to reject

Upper H 0H0

because the​ P-value is

less than or equal toless than or equal to

alphaα.

Answer 1

Given that :

α=0.1

Mean $\mu$ = 75

claim : The mean pulse rate (in beats per minute ) of a certain group of adult males is 75

H0:  $\mu$ = 75

Ha:  $\mu$$\neq$ 75

p value = 0.0893

p value = 0.0893 < α=0.1

Reject Ho

Reject H0 because the​ P-value is less than or equal to less than or equal to alpha α.

Hence option C is correct
