Which diet is the best in terms of weight loss? Low carb or low fat diets ? Discuss the health implications of each.
Two weight loss programs were compared to evaluate whether low fat or low carb diets work better to reduce weight. 12 women were randomly assigned to either the low fat program or the low carb program. After three months, the women’s weight loss in pounds was measured. The results for both groups of women is presented below: Low fat: 10 12 15 17 20 Low carb: 12 9 10 4 6 12 8 Conduct a two tailed test at alpha...
low carb n=77 average weight loss 4.7kg standard deviation7.2kg low fat n=79 average weight loss 2.6kg standard deviation5.9kg For this problem, the degrees of freedom is 147, which gives the critical t-value for a 95% confidence interval to be TC = 1.992. Use this value and the values in the table to calculate the margin of error for the difference in population means: E=Tc s1 2/n1+s22/ n2. Calculate the difference in sample means, x1-x2, using the low-carbohydrate group as group...

Researchers randomly assigned 322 moderately obese volunteers to one of three diets to study how the diets compare with respect to various outcomes such as weight loss, lipid profiles, blood pressure, and other indicators of health and metabolic function. The three diets included a low-carbohydrate diet, a low-fat diet, and a Mediterranean diet that consists of moderate fat and a high proportion of monounsaturated fats. All study participants worked at the same research center in Israel, where lunch (the main...
PLEASE READ THE ARTICLE AND ANSWER THE QUESTIONS CUTTING carbohydrates from your diet could increase the risk of an early death, a study has found. The findings suggest trendy weight loss regimes which encourage avoiding bread, potatoes and pasta may do more harm than good. However, it's not an excuse to pile your plate with them as the study also found that eating too many carbs damages health. Instead, it suggests a moderate amount of carbohydrate, around 50 to 55%...
11. 45 adults used the Atkins weight loss program. After 12 months, the sample mean weight loss was found to be 2.1 lb, with a population standard deviation of 4.8 lb. Construct a 90% confidence interval to estimate the mean weight loss for all such subjects. a) Find the margin of error, E. b) What is the Confidence Interval? c) Interpret the confidence interval.
2. Researchers were interested in evaluating the effects of two low-fat diets with and without resistance exercise training (RT) on weight loss. The diets differed in the carbohydrate-to-protein ratio. A total 80 individuals with type 2 diabetes participated in the study. There were 40 men and 40 women and each group was randomly assigned to an isocaloric diet of either standard or high protein, with or without supervised resistance training (3 days/week) for 16 weeks. Body weight was measured before...
Does this diet help? A group of 78 people enrolled in a weight loss program that involved adhering to a special diet and to a daily exercise program. After six months, their mean weight loss was 27 pounds, with a sample standard deviation of 10 pounds. A second group of 43 people went on the diet but didn't exercise. After six months, their mean weight loss was 15 pounds, with a sample standard deviation of 8 pounds. Construct a 99.9%...
