QUESTION 3 a) Researchers want to test the effect of three different diets on the weight...
c) Plasma estrone plus estradiol (Plasma E1 2) steroid levels were measured in women given estrogen (Premarin) and in a control group of women. The women given estrogen were divided into three treatment groups. One group was given a daily dose of. 0.625 mg, the second group was given 1.25 mg, and the third group was given 2.5 mg. The researchers noted that the plasma steroid levels were not normally distributed, but became so after a logarithm transformation was applied....
Three independent researchers wanted to study the effect of type of diet on weight gain in mice. Each researcher was interested in 3 specific diets: standard mouse chow diet, “junk” food diet, and an organic diet. Each researcher conducted their own study, but they all followed similar procedures. For studies A, B, and C, a total of 66 mice were randomly assigned to receive one of the 3 types of diets (22 in each group). The outcome variable, weight gain...
A group of researchers investigated the impact of every-other-day fasting on weight loss in humans. After 22 days of every-other-day fasting, the researchers measured the amount of weight that was lost by each of 16 human subjects. These data were used to construct a 95% confidence interval for predicting the mean weight loss for the population of people who followed the every-other-day fasting diet for 22 days. The computed interval was (3.4, 4.8) pounds. The interpretation of the interval given...
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...
Want to know the steps for these questions, please?Use the following information for questions 33 – 42.A dietitian wanted to test three different diets to find out whether or not the mean weight loss for each of these diets is the same. He randomly selected 15 overweight persons, randomly divided them into three groups, and put each group on one of the three diets. The table shown below records the weights lost by these persons after being on these diets...
Can you please explain in simple terms the methods of this experiment? I'm having difficulty visualizing and understanding what is being done. I have copied and pasted some of the text from the article. Thank you! Abstract : Obesity, high-fat diets, and subsequent type 2 diabetes (T2DM) are associated with cognitive impairment. Moreover, T2DM increases the risk of Alzheimer's disease (AD) and leads to abnormal elevation of brain beta-amyloid levels, one of the hallmarks of AD. The psychoactive alkaloid caffeine...
