Significance level for the t-test: f. Decision rule: If the significance level of the obtained t statistic is greater than ____ (alpha level), we fail to reject the null hypothesis. If the significance level of the obtained t statistic is equal to or less than ____ (alpha level), we reject the null hypothesis. g. Decision: Since the significance level of the obtained t statistic is _____ and it is __________(greater or less) than ____ (alpha level), we ________(reject or fail to reject) the null hypothesis. h.

Assume a significance level of α=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 70 bpm. The hypothesis test results in a P-value of 0.0025. a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.) Choose the correct answer below. A. Fail to reject H0 because the P-value is less than or equal to α. B. Reject H0 because the P-value is less than or equal to α. C. Reject H0 because the P-value is greater than α. D. Fail to reject H0 because the P-value is greater than α. b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion? A. The mean pulse rate (in beats per minute) of the group of adult males is 70 bpm. B. There is sufficient evidence to warrant rejection of the claim that the…
