Question

40. If a null hypothesis is rejected at the 0.05 level of significance, the. (2 points)

(A) the hypothesis must not be rejected at the 0.02 level of significance

(B) the hypothesis must be rejected at any level of significance

(D) the hypothesis may or may not be rejected at the 0.02 level of significance

41. If a null hypothesis is rejected at the 0.05 level of significance, the. (2 points)

(A) the hypothesis may or may not be rejected at the 0.1 level of significance

(B) the hypothesis would be rejected at the 0.1 level of significance

(D) the hypothesis must not be rejected at the 0.1 level of significance

42. If a null hypothesis is not rejected at the 0.05 level of significance, the. (2 points)

(A) the hypothesis must not be rejected at the 0.1 level of significance

(B) the hypothesis must not be rejected at any level of significance

(D) the hypothesis would be rejected at the 0.1 level of significance

43. If a null hypothesis is not rejected at the 0.05 level of significance, the. (2 points)

(A) the hypothesis must not be rejected at any level of significance

(B) the hypothesis would be rejected at the 0.02 level of significance

(D) the hypothesis may or may not be rejected at the 0.02 level of significance

40. Null hypothesis is rejected if p value is less than alpha

Here it is given that alpha=0.05

So for alpha=0.02 p value may be or not less than alpha.

So answer is.

D) the hypothesis may or may not be rejected at the 0.02 level of significance
