Question

Which of the following statements is true?

I. If the p-value is 0.01, we reject H₀ for any alpha level less than 0.01.

II. If we use an alpha level of 0.05, then a p-value of 0.005 is not statistically significant.

III. If we use an alpha level of 0.05, then we fail to reject the null hypothesis if the p-value is 0.1.

Answer 1

We reject H0 if the p value is less than the level of significance.

I) False, since P value is 0.01, we reject H0 for any alpha level greater than p value not less than P value.

II) False, since P value is less than the alpha level so it will be significant.

III) True, if P value is greater than the alpha level so fail to reject H0.
