Questions 5: (Total Points = 14) A study was conducted to compare three new appetite suppressants (A, B, and C) to a placebo in terms of their effects on weight reduction. The outcome of interest was weight reduction, measured in pounds, using a significance level of 5%. The following data display the number of participants in each group and the results of the analysis of variance (ANOVA) on the collected sample data. A B C Placebo n1 = 10 n2 = 10 13 = 10 14 = 10 Source of Sums of Squares Degrees of freedom Variation (SS) (df) Mean Squares F (MS) Between treatments 625.2 208.4 ?

Specify the type of sample (i.e., one sample or two sample; independent or dependent samples) and outcome variable (i.e., dichotomous or continuous) for this study? b. State the null and research hypothesis for this study. c. What is the degrees of freedom for Between Treatment Variation? d. What is the degrees of freedom for Within Treatment (Error or residual) Variation? e. What is the critical value for the test statistic? f. What is the calculated value for the test statistic? g. What would be the conclusion of the study based on the ANOVA results
