According to the CDC, cholesterol levels can be reduced by following a healthy diet, getting regular exercise, and reducing the amount of alcohol consumed on a weekly basis. One method of monitoring overall cholesterol levels is to calculate your cholesterol ratio (LDL/HDL), in general a cholesterol ratio between 3.5 and 5.0 is considered to be healthy for most adults. Suppose you are a clinical researcher testing the effects of these lifestyle changes on patient cholesterol levels. In order to determine if following these guidelines helps to reduce overall cholesterol, a total of 18 participants (N = 18) with moderate to high cholesterol ratios (i.e., 3.91 to > 5.0) were recruited for a healthy lifestyle study and their cholesterol ratio was calculated three times over a six week period: Week 0 (baseline), Week 3, and Week 6. Using the variables "Week 0", "Week 3", and "Week 6" in the data set, conduct a One-Way, Within Subjects (AKA Repeated Measures) ANOVA, at α = 0.05, to see…

Diabetes is a serious disease that can affect anyone and requires lifelong monitoring. It is estimated that 422 million people worldwide are diabetic, a number four times higher than that registered 40 years ago, according to the World Health Organization (WHO). The fasting blood glucose reference values are: >Normal fasting glucose: less than 99 mg / dL;>Altered fasting glucose: between 100 mg / dL and 125 mg / dL;>Diabetes: equal to or greater than 126 mg / dL;>Low fasting glycemia or hypoglycemia: equal to or less than 70 mg / dL. Assuming that a study was carried out with 120 patients, the mean fasting blood glucose found, by UV-Vis spectrophotometry, was 88 mg / dL, the standard deviation was 30 mg / dL, which is the fraction (%) of patients who have pre-diabetes, blood glucose between 100 and 125 mg / dL?

What do people actually order at Chipotle? How healthy is a normal Chipotle meal? Chipotle and other relatively new fast casual chains like Shake Shack, Potbelly and Five Guys typically promote themselves as having healthier menu choices than the traditional fast food outlets like McDonald's, Taco Bell, Burger King, etc.The recommended daily calorie intake for most adults is 1,600 to 2,400. The histogram below shows the calories in approximately 3,000 meals ordered from Chipotle on Grubhub.While the histogram is not perfectly symmetric (there is mild right skewness), it is close enough to being symmetric and bell-shaped to justify using the 68-95-99.7 rule. Suppose the distribution of calories in a Chipotle meal can be considered symmetric and bell-shaped with mean 1079 calories and standard deviation 296 calories. Use the 68-95-99.7 rule to answer the following questions.a. What is the approximate percentage of the Chipotle meals that have between 487 and 1671 calories?b. The middle…

You may need to use the appropriate appendix table or technology to answer this question. Advertisers contract with internet service providers and search engines to place ads on websites. They pay a fee based on the number of potential customers who click on their ad. Unforțunately, click fraud-the practice of someone clicking on an ad solely for the purpose of driving up advertising revenue–has become a problem. Businessweek reports that 4C percent of advertisers claim they have been a victim of click fraud. Suppose a simple random sample of 390 advertisers will be taken to learn more about how they are affected by this practice. (Round your answers to four decimal places.) (a) What is the probability that the sample proportion will be within ±0.04 of the population proportion experiencing click fraud? (b) What is the probability that the sample proportion will be greater than 0.45?
1.In a national survey of 2013 adults, 1283 indicated that they believe rudeness is a more serious problem than in years past. Does this indicate that more than three-quarters of American adults believe rudeness is a worsening problem?
As humans we consume food. The body extracts good things such as proteins and vitamins and throws away waste. A typical waste product is uric acid. High levels of uric acid can be an indication of conditions such as gout, kidney disease, and cancer. For females a high level of uric acid is 6 mg/dL or more and for males a high level of uric acid is 7 mg/dL or more. Suppose, over a period of months, an adult male was given 9 blood tests for uric acid. The results of each blood test are shown below. results 10.24 10.1 11.19 11.1 9.34 9.58 9.63 10.59 9.58 The distribution of uric acid in healthy adult males is normally distributed with known population standard deviation, σ=1.15σ=1.15 mg/dl.Find a 95% confidence interval for the population mean of uric acid in this adult male's blood. Assume the sample of blood tests were given in a way that's equivalent to a simple random sample. (Round your answers to two decimal places.) margin of error ? mg/dLlower limit? mg/dLupper limit?…
