Suppose a hypertension trial is mounted and 18 participants are randomly assigned to one of the comparison treatments. Each participant takes the assigned medication and their systolic blood pressure (SBP) is recorded after 6 months on the assigned treatment. The data are presented in the table below. Compute the totals for each column (1pt).

Group 1 Standard Treatment : 124 111 133 125 128 115 = 736

Group 2 Placebo: 134 143 148 142 150 160 = 877

Group 3 New Treatment: 114 117 121 124 122 128 = 726

Is there a difference in mean SBP among treatments at a 5% significance level?

Indicate the correct competing hypotheses:

Compute Error Sums of Squares For Each Group:

Complete the ANOVA table:

True or false: We have statistically significant evidence at α=0.05 to show that there is a significant difference in mean SBP among the treatment groups

A clinical trial is run to compare weight loss programs and participants are randomly assigned to one of the four comparison programs and are counseled on the details of the assigned program. Three popular weight loss programs were considered: the low calorie diet, the low fat diet, and the low carbohydrate diet . For comparison purposes, a fourth group is considered as a control group. Participants in the fourth group are told that they are participating in a study of...

1. A clinical trial is run to compare weight loss programs and participants are randomly assigned to one of the comparison programs and are counseled on the details of the assigned program. Participants follow the assigned program for 8 weeks. The outcome of interest is weight loss, defined as the difference in weight measured at the start of the study (baseline) and weight measured at the end of the study (8 weeks), measured in pounds. Three popular weight loss programs...

In a comparison of two different weight-loss programs, obese participants were randomly assigned to one of two groups: (1) the soy group, a low-calorie group that ate only soy-based proteins, or (2) the traditional group, a low-calorie group that received 2/3 of their protein from animal products and 1/3 from plant products. One of the dependent measures collected was the amount of body fat loss as a percentage of initial body weight. Summary data from each group based on this...

Forty-eight participants were randomly assigned to do math tasks under one of three conditions: 16 while listening to soft gentle music, 16 while listening to loud intense music, and 16 while in silence. The means and estimated population variances for the three groups were: Soft-gentle: M = 33, S2 = 25; Loud-intense: M = 42, S2 = 36; Silence M = 42, S2 = 16. Do these results suggest that there is a difference in performance on this kind of...

Researchers conducting a clinical trial randomly assigned 60 patients with painful knee osteoarthritis evenly into one of three treatment groups: glucosamine, chondroitin, or placebo.After the study period, patients were asked if they experienced substantial improvement in pain and ability to function normally.Thirty-four patients replied that they did have an improvement, including 13 in the glucosamine group, 16 in the chondroitin group, and 5 in the placebo group. List a potential confounding variable for this study and briefly explain a possible...
