Mark the statement below as True or False. If you believe that the statement is false, briefly explain why you think it is false.

If both sample sizes are doubled, the chance that the null hypothesis is falsely rejected when using the two-sample t-test is reduced.

Choose the correct answer below.

A. The statement is false. If both sample sizes are doubled, the chance of incorrectly failing to reject of the null hypothesis when using the two-sample t-test is decreased.

B. The statement is false. The change for a false positive error is determined by the value of α and not by the sample size.

C. The statement is true.

D. The statement is false. If both sample sizes are doubled, the chance of a false rejection of the null hypothesis when using the two-sample t-test is increased.
