B. have made a Type I error

C. reject the null hypothesis

D. retain the null hypothesis

(Pt. 2) If we reject the null hypothesis when in reality the null hypothesis is true, we have:

A. made a Type 2 error

B. made a Type 1 error

C. made the correct decision

D. none of the above

(Pt. 3) If we retain the null hypothesis when in reality the null hypothesis is false, we have:

A. claimed a difference when none exists in the population

B. committed a Type II error

C. miscalculated

D. committed a Type I error

(Pt. 4) If we retain the null hypothesis when in reality the null hypothesis is true, we have:

A. made the correct decision

B. made a Type 2 error

C. made a Type 1 error

D. none of the above

Explanation / Answer

1) If our obtained/calculated positive t value is greater than our critical positive t value, we reject the null hypothesis

2) If we reject the null hypothesis when in reality the null hypothesis is true, we have made a Type 1 error

3) If we retain the null hypothesis when in reality the null hypothesis is false, we have committed a Type II error

4) If we retain the null hypothesis when in reality the null hypothesis is true, we have made the correct decision
