Question 4 1 Point If the test statistic F follows an F-distribution with df1=4 and df2=5, what is the value of F for which 0.95 of the area lies below? A) 15.5291 B 5.1922 C 0.05 D 6.2561 E 11.3919 Question 5 1 Point You carried out an ANOVA on a preliminary sample of data. You then collected additional data from the same groups, the difference being that the sample sizes for each group were increased by a factor of 10, and the within-group variability has decreased substantially. Which of the following statements is NOT correct. A 5SW has decreased. B The critical value F* has changed. C The test statistic F has changed. D The degrees of freedom associated with the within groups term has increased. E The degrees of freedom associated with the between groups term has increased. Question 6 1 Point If the sample means for each of k treatment groups were identical (yes, this is extremely unlikely), what would be the observed value of the ANOVA test statistic? A A negative value Infinite C A value between 0.0 and 1.0 D 1.0 E 0.0
