WebThe F statistic and its p value tell us whether the simple regression model is significant. B. The p value of F can never be negative. C. The F statistic is the ratio of two variances. D. The F-test gives a different p-value than the t-test. The … WebP-value ≤ α: The difference between the means is statistically significantly (Reject H 0) If the p-value is less than or equal to the significance level, the decision is to reject the null hypothesis. You can conclude that the difference between the population means does not equal the hypothesized difference.
