A study is conducted to compare mean cholesterol levels for individuals following a low-carbohydrate diet for at least 6 months to individuals following a conventional (low-fat, low-calorie) diet for at least 6 months. The data are summarized here:

Diet Program

Sample Size

Mean Cholesterol

Standard Deviation Cholesterol

Low carbohydrate

50

225.4

24.5

Conventional

75

203.8

21.6

Using the five-step approach to hypothesis testing, test if there is a significant difference in mean cholesterol levels between the diet programs using a 1% level of significance for alpha.

Calculate the appropriate test statistics for this study. You must show all your calculations to receive points.

[a] Test statistic = – 5.19

[b] Test Statistic = – 5.59

[c] Test Statistic = 5.19

[d] Test Statistic = 5.59

Solutions

Expert Solution

Hence the value of test statistics is 5.059.

Note: please check the option that you have provide because the value of test statistics is 5.059 not 5.59.

A study was conducted to investigate whether a new diet lowers cholesterol. The researchers took a random sample of 100 subjects with high cholesterol and measured the cholesterol levels for each. Then each subject began the new diet as instructed. After six months, the subjects' cholesterol levels were measured again. The differences in cholesterol level, calculated as After - Before, follow an approximately normal distribution. Suppose a 99% confidence interval for the mean cholesterol difference is (-13.89, -7.66). Which of...

A study was conducted to compare the effect of three levels of digitalis on the level of calcium in the heart muscle of dogs. A description of the actual experimental procedure is omitted, but it is sufficient to note that the general level of calcium uptake varies from one animal to another so that comparison of digitalis levels (treatments) had to be blocked on heart muscles. That is, the heart muscle of a dog was regarded as a block, and...

The Okinawan diet can be described as a low-energy, nutrient-rich, high-carbohydrate diet that may be beneficial for reducing the risk of many chronic diseases. The Acceptable Macronutrient Distribution Range (AMDR) for carbohydrate is 45% to 65% of kcal. What percent of calories in this 1-day Okinawan diet menu come from carbohydrate? The amount of total carbs is 342.6 and the amount of total calories is 1790.5. (I wasn't provided with the amount of calories per gram of carbohydrate.)

Data from the Framingham Study allow us to compare the distributions of initial serum cholesterol levels for two populations of males: those who go on to develop coronary heart disease and those who do not. The mean serum cholesterol level of the population of men who do not develop heart disease is µ = 206mg/10ml and the standard deviation is σ = 36mg/100ml. Suppose, however, that you do not know the true population mean; instead, you hypothesize that µ is...
