3. Serum cholesterol levels above 200 mg/dl are considered high. A study is being planned to determine if the mean cholesterol level for adult Canadians exceeds 200. If a t-test is to be used with α= 0.05, what sample size is required to detect a mean cholesterol level as high as 218 with power .95? An earlier study estimated the standard deviation of cholesterol levels among Canadian adults to be about 58.2
what percent of adults do you expect to have cholesterol levels between 150 and 160 mg/dL The cholesterol levels of an adult can be descebed by a normal model with a mean of 181 mg/d and a standard deviation of 21. 130 22 2 b) What percent of adults do you expect to have cholesterol levels over 200 mg/d? 18.41% Round to two decimal places as needed ) c) What percent of adults do you expect to have cholesterol levels...
In a study to assess the effectiveness of garlic for lowering cholesterol, 50 adults were treated with garlic tablets. Cholesterol levels were measured before and after treatment. The changes in their LDL cholesterol (in mg/dL) have a mean of 8 and a standard deviation of 4. (a) Construct a 95% interval estimate of the mean change in LDL cholesterol after the garlic tablet treatment. (Round the lower bound and upper bound of the confidence interval to two decimal places) Include...
Kevin's total blood cholesterol level is 190 mg/dL and his HDL cholesterol levels is 60 mg/dL. According to this information: He should reduce his cholesterol intake His cholesterol is in an unhealthy range He should consider taking cholesterol medication His blood cholesterol levels are in a great range to be protective against heart disease
According to a recent poll, 25% of adults in a certain area have high levels of cholesterol. They report that such elevated levels "could be financially devastating to the regions healthcare system" and are a major concern to health insurance providers. According to recent studies, cholesterol levels in healthy adults from the area average about 210 mg/dL, with a standard deviation of about 30 mg/dL, and are roughly Normally distributed. Assume that the standard deviation of the recent studies is...
Assume that the total cholesterol levels for adults are normally distributed with mean cholesterol level of 51.5 mg/dL and standard deviation 14.3 mg/dL. Find the probability that an individual will have a cholesterol level greater than 58 mg/dL
(6 points) Total cholesterol levels less than 2.00x 10 milligrams per deciliter (mg/dL) are considered desirable for adults. Use this border-line concentration to calculate how many grams of total cholesterol the individual's body may contain if the total blood volume of the individual is 5.4 L. 8.
According to a recent poll, 27% of adults in a certain area have high levels of cholesterol. They report that such elevated levels "could be financially devastating to the regions healthcare system" and are a major concern to health insurance providers. Assume the standard deviation from the recent studies is accurate and known. According to recent studies, cholesterol levels in healthy adults from the area average about 205mg/dL, with a standard deviation of about 30mg/dL, and are roughly Normally distributed....
Assume total cholesterol levels (TChol) are normally distributed with mean μ = 215 mg/dl and standard deviation σ = 30 mg/dl for the adult American population. That is, TChol ~ N(215, 302). Total cholesterol values of 240 mg/dl or greater are considered high; and levels in the range of 200 to 240 are called borderline high. a. What proportion of this population do we expect to find with high cholesterol? What proportion do we expect to find with borderline high...
