The degrees of freedom here is computed as:
Df(numerator) = k - 1 = 3 - 1 = 2
Df(denominator) = n - k = 12*3 - 3 = 33
Therefore 2, 33 is the required number of degrees of freedom here for the F test here.

Question 2 1 pts For an independent-measures ANOVA comparing four treatment conditions, dfbetween=3. True False Next For an analysis of variance comparing four treatment means with a separate sample of a participants in each treatment, the F-ratio will have df - 3.31, 8 True False Next →
Question 32 1 pts An ANOVA is used to evaluate the mean differences among three treatment conditions with a sample of n = 12 participants in each treatment. For this study, what is dfwithin? 11
A researcher conducts an experiment comparing three treatment conditions. The data consist of n = 34 scores for each treatment condition. a. If the researcher used an independent-measures design, then how many individuals were needed for the study and what are the df-values for the F-ratio? Explain in detail and be sure to show all formulas with symbols (and plug in numbers), steps, processes and calculations for all steps and all parts of all answers. b. If the researcher used...
Question 12 0 pts Suppose a hypertension trial is mounted and 18 participants are randomly assigned to one of the comparison treatments so that each treatment group has 6 participants. Each participant takes the assigned medication and their systolic blood pressure (SBP) is recorded after 6 months on the assigned treatment. The ANOVA table is as follows (You should be able to figure out values in the numbered cells): Source Between-Group 2376.8 Within-Group 846.2 Total Sum of Squares df Mean...
