Question 24(1 point)

Which of the following statements is not true?

Question 24 options:

a) The p-value of a significance test gives an indication of the probability that that the null hypothesis in not valid.

b) A leveltwo-sided hypothesis test rejects a null hypothesis (H0 :=0) exactly when the value0falls outside the level C = 1 -confidenceinterval for

c) According to the Central Limit Theorem, the sampling distribution of the sample mean is approximately normal when the sample size is large

Question 25(1 point)

Suppose you reject the null hypothesis at the= 0.01 significance level. Would you reject it at the= 0.05 level?

Question 25 options:

a) Yes, because thep-value would have to be less than 0.050.

b) Yes, because thep-value would be greater than 0.05.

c) No, because thep-value would be greater than 0.05.

d) We cannot tell without knowing thep-value.
