19. Assume that a null hypothesis is false. Which one of the following statements is true?

a. A study with a larger sample is more likely than a smaller study to get the result that P < 0.05.

b. A study with a larger sample is less likely than a smaller study to get the result that P < 0.05.

c. A study with a larger sample is equally likely compared to a smaller study to get the result P < 0.05.

Answer : C

C, because of the definition of p-value.

(Under Ho, the probability that P is less that 0.05 is... 5%.)
