## Understanding Confidence Intervals in Cholesterol Studies### Study OverviewIn a research study assessing the effectiveness of garlic in lowering cholesterol, 42 participants were given garlic in a processed tablet form. Their cholesterol levels were measured both before and after treatment. The focus was on changes in LDL cholesterol (measured in mg/dL), which had a mean of 2.9 and a standard deviation of 16.7. The aim is to construct a 95% confidence interval estimate of the mean net change in LDL cholesterol after administering the garlic treatment.### Research Questions- **What does the confidence interval indicate about garlic's effectiveness in reducing LDL cholesterol levels?**### Helpful Resources- [t Distribution Table](#)- [Standard Normal Distribution Table - Page 1](#)- [Standard Normal Distribution Table - Page 2](#)### Confidence Interval Calculation**Question:** What is the confidence interval estimate of the population mean $ \mu $?\[ \text{mg/dL} < \mu < \text{mg/dL} \]*(Round to two decimal places as needed.)*#### Instructions- Enter the calculated values into the fields and click "Check Answer."This exercise will help you understand how confidence intervals are used in medical studies to assess treatment effectiveness.

In a test of the effectiveness of garlic for lowering cholesterol, 42 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before - after) in their levels of LDL cholesterol (in mg/dL) have a mean of 2.9 and a standard deviation of 16.7. Construct a 95% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment.

What is the test statistic and p-value? Because the P-value is ▼ greater less than the significance level 0.05, there ▼ is not is sufficient evidence to support the claim that there is a linear correlation between selling price (in hundred thousands) and the list price (in hundred thousands) of homes sold for a significance level of α=0.05.
In a test of the effectiveness of garlic for lowering cholesterol, 36subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes (before minus after) in their levels of LDL cholesterol (in mg/dL) have a mean of 0.3 and a standard deviation of 2.39. Use a 0.01 significance level to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the garlic treatment? Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.
The heart rate of 20 patients in the ICU have a mean of 95.3 beats per minute and a standard deviation of 19.6 beats per minute. Are heart rates from the ICU patients unusual given a normal heart rate has a mean of 72 beats per minute? What is the t-stastic?
Á study was conducted that examined the relationship between alcohol consumption and risk of heart attack. In all, 417 men, age 40 or older, were tracked over ten years and the number of that experienced a heart attack was recorded. The participants were grouped by those who totally abstained from alcohol and those that drank moderately. For the results given in the table below, use the chi-squared test to find the p value for NHST at the .05 level. (In SPSS use the Yates continuity correction value.)

Diabetes Plasma-glucose levels are used to determine the pres- ence of diabetes. Suppose the mean In (plasma-glucose) concentration (mg/dL) in 35- to 44-year-olds is 4.86 with standard deviation = 0.54. A study of 100 sedentary people in this age group is planned to test whether they have a higher or lower level of plasma glucose than the general population. 7.7 If the expected difference is 0.10 In units, then what is the power of such a study if a two-sided test is to be used with a = .05? 7.8 Answer Problem 7.7 if the expected difference is 0.20 In units. 7.9 How many people would need to be studied to have 80% power under the assumptions in Problem 7.7?
The Merck Manual states that, for healthy adults, the mean number of milliliters of oxygen per deciliter of blood is 19.0. A company that sells vitamins claims that its multivitamin complex will increase the oxygen capacity of the blood. A random sample of 28 adults took the vitamin for six months. After blood tests, it was found that the sample mean was 20.7 ml of oxygen per deciliter of blood with a standard deviation of 6.7ml. a. At the 0.05 level, test the claim that the average oxygen capacity has increased. b. How much power do you have to detect a 3ml difference (from the null) in the average amount of oxygen in the blood? c. What sample size would you need to have 90% power to detect this observed difference?
