Cholesterol 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.

UNIT 5 CHAPTER 8 The Porsche Club of America sponsors driver education events that provide high-performance driving instruction on actual racetracks. Because safety is a primary consideration at such events, many owners elect to install roll bars in their cars. Deegan Industries manufactures two types of roll bars for Porsches. Model DRB is bolted to the car using existing holes in the car's frame. Model DRW is a heavier roll bar that must be welded to the car's frame. Model DRB requires 20 pounds of a special high-alloy steel, 40 minutes of manufacturing time, and 60 minutes of assembly time. Model DRW requires 25 pounds of the special high-alloy steel, 100 minutes of manufacturing time, and 40 minutes of assembly time. Deegan's steel supplier indicated that at most 40,000 pounds of the high-alloy steel will be available next quarter. In addition, Deegan estimates that 2000 hours of manufacturing time and 1600 hours of assembly time will be available next quarter. The profit…
give handwritten answer of the question-Which one of the following is the most used model or calibration curve for a one-component system in quantitative analysis? Y = bo + b1X1 + b2X2 + error Y = bo + b1X + b1X2 + error Y = bo + b1X + error Y = bo + b1X1 + b2X2 + b3X1X2 + error
Consider a hypothetical study that suggests that job satisfaction predicts the extent to which employees perform well on the job. A follow-up investigation supports the mechanism underlying this relationship: satisfied employees show up to work more energized, which in turn goes on to influence their performance. In the space below, match the variables in the study with the corresponding name. Independent variable a. Energy at work b. job performance c. job satisfaction d. This type of variable is not mentioned in this example Mediator variable a. Energy at work b. job performance c. job satisfaction d. This type of variable is not mentioned in this example
Two employees (Molly and Jim) must conduct a data analysis project on the success of a firm’s marketing efforts and then write a report of their findings for consideration by the firm’s board. If the first employee, Molly, worked completely alone, she could finish the data analysis component of the project with 30 hours of work and could write the report with an additional 10 hours of work. If Jim worked alone, he would take 48 hours of work to conduct the data analysis and then 12 hours to write the report. Assume that both employees need to contribute to the project, that there would be no benefits to having two people work on the same part of the project (data analysis and writing), and that working on the two parts are independent (i.e. there is no benefit to working on both parts). Which employee has the comparative advantage in conducting the data analysis? Explain
You hypothesize that there may be a non-linear relationship between your predictors, where there may be more mosquitoes in sites with water and with caribou hosts. How do you create your model? Assume that "caribou" corresponds to the presence/absence of caribou Assume that "water" corresponds to the presence/absence of water number of mosquitoes ~ caribou * water number of mosquitoes ~ caribou + water presence/absence of mosquitoes ~ caribou + water presence/absence of mosquitoes ~ caribou * water
Company A receives large shipments of microprocessors from Company B. It must try to ensure the proportion of microprocessors that are defective is small. Suppose Company A decides to test 10 microprocessors out of a shipment of thousands of these microprocessors. Suppose that if at least one of the microprocessors is defective, the shipment is returned. Complete parts a through c.a. If Company B's shipment contains 8% defective microprocessors, calculate the probability the entire shipment will be returned.The probability is0.5656.(Round to four decimal places as needed.) I only need answer to B below:b. If Company B and Company A agree that Company B will not provide more than 3% defective chips, calculate the probability that the entire shipment will be returned even though only 3% are defective.The probability is (Round to four decimal places as needed.)
A quality control engineer studied the relationship between years of experience as a system control engineer and the capacity of the engineer to complete within a given time a complex control design including the debugging of all computer programs and control devices. A group of 25 engineers having widely differing amounts of experience (measured in months of experience) was given the same control design project. The results of the study are given in the following table with y = 1 if the project was successfully completed in the allocated time and y = 0 if the project was not successfully completed. a. Determine whether experience is associated with the probability of completingthe task. b. Compute the probability of successfully completing the task for an engineer having 24 months of experience. Place a 95% confidence interval on your estimate.
We have a random sample of data on women living in NSW in 2020. During the period covered by our data there were COVID lockdowns in some areas but not in other areas. These lockdowns closed schools and required all but essential workers to work from home or stay at home and not work if they could not work from home. Our data contains the following variables: hours = a woman’s number of hours of work per week kids = a woman’s number of children living at home lockdown = a dummy variable equal to one if the woman is living in an area under a lockdown order and 0 is she is living in an area not locked down. We consider the model: hours = β0 + β1lockdown + β2kids + β3lockdown∗kids + u Which of the following measures the effect of the number of children on hours of work for women living in areas that were locked down? a) β0 b) β2 c) β2 + β3 d) β3 e) none of the other possible answers are correct
A group of 11 students was selected at random and asked for their high school GPA and their freshmen GPA in college the subsequent year. The results were: Student High School GPA Freshmen GPA 1 2.0 1.6 2 2.2 2.0 3 2.6 1.8 4 2.7 2.8 5 2.8 2.1 6 3.1 2.0 7 2.9 2.6 8 3.2 2.2 9 3.3 2.6 10 3.6 3.0 We would like to know whether there is a linear relationship between the high school GPA and the college freshmen GPA, and we would like to be able to predict the freshmen GPA, if we know that the high school GPA of another student is, say, 3.4. Provide the two requested scatter plots for this data (put college freshman GPA on the Y (vertical) axis!). a) What would be your approximate 95% prediction interval for question (g)? b) Show your scatterplot with the predicted trend line below
