dietitian wishes to see if a person’s cholesterol level will change if the diet is supplemented by a certain mineral. Five randomly selected subjects were pre-tested, and then they took the mineral supplement for a 6-week period. The Cholesterol level before and after taking the mineral supplements are shown in table below. (Cholesterol level is measured in milligrams per deciliter).
Subject: 1 2 3 4 5

Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken
when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood
pressures were measured, in millimeters, for a sample of 7 adults. The following table presents the results. Do people with higher
diastolic pressure tend to have higher or lower systolic pressures?

The least-squares regression line y =b,+b,x=6.1772+0.6247x and E (x-x) = 735.4286 are known for these data. Use the
P-value method to test H:B, =0 versus H, :B, ± 0. Can you condlude that systolic blood pressure is useful in predicting diastolic
blood pressure? Use the a=0.01 level of significance.

- Diet Program Nicole started a new diet that requires each meal to have 460 calories, 6 g of fiber, and 11 g of fat. The table shows the fiber, fat, and Calorie content of one serving of each of three breakfast foods. How many servings of each food should Nicole eat to follow her diet!arrow_forwardCholesterol Cholesterol in human blood is necessary, but too much can lead to health problems. There are three main types of cholesterol: HDL (high-density lipoproteins), LDL (low-density lipoproteins), and VLDL (very low-density lipoproteins). HDL is considered “good” cholesterol; LDL and VLDL are considered “bad” cholesterol. A standard fasting cholesterol blood test measures total cholesterol, HDL cholesterol, and triglycerides. These numbers are used to estimate LDL and VLDL, which are difficult to measure directly. Your doctor recommends that your combined LDL/VLDL cholesterol level be less than 130 milligrams per deciliter, your HDL cholesterol level be at least 60 milligrams per deciliter, and your total cholesterol level be no more than 200 milligrams per deciliter. (a) Write a system of linear inequalities for the recommended cholesterol levels. Let x represent the HDL cholesterol level, and let y represent the combined LDL VLDL cholesterol level. (b) Graph the system of inequalities from part (a). Label any vertices of the solution region. (c) Is the following set of cholesterol levels within the recommendations? Explain. LDL/VLDL: 120 milligrams per deciliter HDL: 90 milligrams per deciliter Total: 210 milligrams per deciliter (d) Give an example of cholesterol levels in which the LDL/VLDL cholesterol level is too high but the HDL cholesterol level is acceptable. (e) Another recommendation is that the ratio of total cholesterol to HDL cholesterol be less than 4 (that is, less than 4 to 1). Identify a point in the solution region from part (b) that meets this recommendation, and explain why it meets the recommendation.arrow_forward#1. A baseball team won 9 out of 23 games.

A study is carried out to analyze whether the type of painting, among three types available, affects the hardness of a certain type of enamel. The firing of the parts is done in an oven with four trays, one above another, and with 15 parts on each. Since it can be assumed that the tray might have an influence on the result, because of its position in the oven, a blocked design is used putting five parts of each type of painting on each tray. The following hardness measures are obtained: Photo Does the type of painting and the tray on which the parts are placed affect the mean hardness of the enamel paint?

- Experiment Terminology Researchers wanted to know which treatment is more effective for relieving joint pain: an ibuprofen pill, or a newly-developed topical ointment rubbed on the affected joint. Fifty subjects agreed to participate in the experiment. Researchers had the following supplies on hand: real ibuprofen pills; pills that looked and tasted like ibuprofen pills but which were actually made of an inert substance; the real topical ointment; a topical ointment that looked and felt like the real ointment but which actually has no affect on the body. Twenty-five of the subjects were randomly selected to take the real pills and use the fake ointment. The remaining twenty-five used the fake pills and the real ointment. The subjects did not knew that they were using one real and one fake item, but they did not know which was which.
