Question

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 68 bpm. The hypothesis test results in a​ P-value of 0.0661.

a. State a conclusion about the null hypothesis.​ (Reject H 0 or fail to reject  H 0​.) Choose the correct answer below.

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

Answer 1

Given:

a) Significance level, = 0.1

P-value = 0.0661

Hypothesis test:

Null hypothesis, H0 : = 68

Alternative hypothesis, Ha : 68

We reject the null hypothesis when the p-value is less than the level of significance.

Here p - value is less than significance level so we reject H0.

b) 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 68 bpm.
