All false. Reconsider the previous exercise. Now suppose that the p-value from the ANOVA F-test turns out to be 0.003. All of the following statements are false. Explain why each one is false. a. The probability is 0.003 that the four groups have the same mean score. b. The data provide very strong evidence that all four fonts produce different mean scores c. The data provide very strong evidence that the comic sans font produces a different mean score than the other fonts. d. The data provide very little evidence that at least one of these fonts produces a different mean score than the others. e. The data do not allow for drawing a cause -and -effect conclusion between font and exam score. f. Conclusion from this analysis can be generalized to the population of all students at the instructor's school. All false. Reconsider the previous exercise.
