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.
What is a unique advantage of the Latin Square design? It reduces the carryover effect while maximizing the strength of the IV manipulation. The Latin Square design uses multiple langauges. It counterbalances while reducing the number of groups/people needed to control for order effects. It is useful in an independent groups designs when matching participants on the dependent variable.

The interaction effect in a factorial design is considered, because it may modify the main effects of the independent variables. True False
Data was collected for 40 randomly selected trees growing in the median strip of a busy freeway. The height of each tree (in inches) was recorded. Data was recorded to the nearest whole inch. The data is summarized in the histogram below. Based on this histogram, determing the minimum and maximum possible tree heights for the recorded data. Note: Each class contains its lower class boundary, but not its upper class boundary.Minimum tree height = inchesMaximum tree height = inches
A researcher wants to examine the effect of humidity on amount of hair frizz. How could the researcher address this question using a multiple-groups design? What are the pros and cons of this design choice? What is/are the appropriate analysis/analyses? How could the researcher address this question using a dependent multiple-groups design? What are the pros and cons of this design choice? Address whatever design you select or consider both types of dependent multiple-groups designs. What is/are the appropriate analysis/analyses?
In 2003 and 2017 a poll asked Democratic voters about their views on the FBI. In 2003, 45% thought the FBI did a good or excellent job. In 2017, 74% of Democratic voters felt this way. Assume these percentages are based on samples of 1300 Democratic voters. Complete parts (a) through (d) below. a. Can we conclude, on the basis of these two percentages alone, that the proportion of Democratic voters who think the FBI is doing a good or excellent job has increased from 2003 to 2017? Why or why not? A. No. Although a lesser percentage is present in the sample, the population percentages could be the same or even reversed. B. No. Although a lesser percentage is present in the sample, the population percentages could be the same, but could not be reversed. C. No. Since a greater percentage is present in the sample, we cannot conclude that a lesser percentage of Democratic voters who think the FBI is doing a good or excellent job is present in the population. D. Yes. Since a lesser…

v Financial has released a summary of investor and investment package information from the past fiscal year. During this time, Westminster provided a choice among 12 pre-designed investment packages. The investment packages were classified according to two variables: riskiness of investment package Westmi chosen ("Risky", "Moderate/mixed", and "Conservative") and age of investor ("Under 35", "35-49", or "50+"). Suppose that we're interested in the possible relationship between the age of the investor and the riskiness of the investment package the investor chose. The following contingency table gives a summary of the information released by Westminster regarding age and riskiness of investment package for 150 investors. In the cells of the table are the respective observed frequencies, and three of the cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, riskiness of investment package chosen and age of investor, are independent. Round your…

Researchers studying the number of electric fish species living in various parts of the Amazon basin were interested in whether the presence of tributaries affected the local number of electric fish species in the main rivers (Fernandes et al. 2004) They counted the number of electric fish species above and below the entrance point of a major tributary at 12 different river locations.
