Question

You use software to carry out a test of significance. The program tells you that the ?P‑value is ?=0.011P=0.011 . This result is

A) not statistically significant at either ?=0.05α=0.05 or ?=0.01α=0.01 .

B) statistically significant at ?=0.05α=0.05 but not at ?=0.01α=0.01 .

C) statistically significant at both ?=0.05α=0.05 and ?=0.01α=0.01 .

D) statistically significant at ?=0.01α=0.01 but not at ?=0.05α=0.05 .

Answer 1

ANSWER:

P-value =0.011

• Since p-value is 0.011 is less than alpha value is 0.05.

p-value< alpha value ,we rejected null hypothesis .

• Since p-value is 0.011 is greater than alpha value is 0.01 ,

P-value > alpha value ,we do not reject null hypothesis

hence the correct option is (b)

Statistically significant at α = 0.05 but not at α = 0.01
