46. Suppose that the p-value of a test of significance is 0.025. Which of the following is correct regarding the conclusions we can draw? a. Results are significant at a significance level of 0.01 but not 0.05 b. Results are significant both at a significance level of 0.01 and 0.05 c. Results are significant at a significance level of 0.05 but not 0.01 d. Results are not significant at a significance level of 0.01 nor 0.05 Answer:

The p-value is the probability of obtaining test results at least as extreme as the observed results, assuming that the null hypothesis is true. A result is considered statistically significant if the p-value is less than the chosen significance level (α). Show more…

15. A significance test gives a P-value of 0.023. This means that the result is statistically significant at (a) both the 0.01 and the 0.05 levels. (b) neither the 0.01 nor the 0.05 levels. (c) the 0.05 level but not at the 0.01 level. (d) the 0.01 level but not at the 0.05 level.

A significance test gives a P-value of 0.023. This means that the result is statistically significant at both the 0.01 and the 0.05 levels. The result is significant at the 0.05 level but not at the 0.01 level. The result is not significant at the 0.05 level but is significant at the 0.01 level.
If the p-value of a test is 0.022 , what is your decision? Select one: a. Reject H0 at 0.05 significance level. b. Reject H1 at 0.01 significance level. c. Cannot reject H1 at 0.01 significance level. d. Cannot reject H0 at 0.05 significance level. e. Reject H0 at 0.01 significance level. f. Cannot reject H1 at 0.05 significance level.
