WebDec 27, 2024 · From the output table we see that the F test statistic is 2.358 and the corresponding p-value is 0.11385. Since this p-value is not less than 0.05, we fail to reject the null hypothesis. This means we don’t have sufficient evidence to say that there is a statistically significant difference between the mean exam scores of the three groups. WebKey Result: P-Value In these results, the null hypothesis states that the mean hardness values of 4 different paints are equal. Because the p-value is less than the significance level of 0.05, you can reject the null hypothesis and conclude that some of the paints have different means.
