Question

For a t-statistic = 3.20 with 10 degrees of freedom, what would be the appropriate statement about the significance level? A) p > .01 B) p < .01 C) p < .05 D) p > .05

Quizplus · Accepted Answer

With 10 degrees of freedom, the critical value for a two-tailed test at the 0.01 level of significance is +/-3.169. Since the calculated t-statistic of 3.20 is greater than the critical value, we reject the null hypothesis and conclude that the result is statistically significant at the p < 0.01 level.
