To further elaborate the regression model, the researchers of the research projectidentified that the factors can be categorized as psychosocial and political-economicfactors. The Psychosocial factors were the freedom, generosity, family and lifeexpectancy while the political-economic factors were GDP per Capita and GovernmentCorruption. To make sense of the factor distinctions, the researcher placed thepsychosocial factors as predictors while the political-economic factors as mediators,thereby, implementing a mediation analysis.A. Which among the political-economic factors can be considered significantmediators between psychosocial factors and happiness? Provide parameterestimates and p-values.B. Using the Total-Indirect Effects table, which among the psychosocial factors(predictors) have significant indirect effects towards happiness? Provide parameterestimates and p-values.C. Describe why the mediators significantly mediate the relationships in 6A. Provide atleast 2 research literature or articles per mediator.D. Based on your answer to 6B, why is the effect of the psychosocial factors of "indirectnature" towards happiness. Provide at least 2 research literature or articles per eachpredictor.

Researchers ran a multiple linear regression to determine if belief accuracy in a political claim when given misinformation was related to the following independent variables: One’s level of anger (coded low = 0, high = 1) One’s level of anxiety (coded low = 0, high = 1) Whether the source of misinformation about the claim came from their own political party (in-party, coded from the other party = 0, from their party = 1) Whether or not a correction of misinformation was made (coded correction without evidence = 0, correction with evidence = 1) One’s political knowledge (continuous measurement from 0-4) One of the two issues in question (coded illegal immigration = 0, death penalty = 1) 4.

I am determining how effective a Drug is at reducing inflammation in individuals infected with a virus. the serum levels of antibody are measured as a measure of inflammation (less antibodies means less inflammation which decreases virus mortality) in 30 people given placebo, 30 people given 1 unit of the drug, and 30 people given 2 units of the drug. I would like to determine what levels of the drug are effective, and if there are sex-specific effects. What are the dependent and independent variables in this experiment? age _________ sex __________ antibody level _____________ treatment ___________
A researcher conducts a survey examining eating and sleeping behavior as well as academic performance for a group of elementary school children. The results of the survey indicate that the children who eat a more nutritious breakfast tend to have better grades than the children who have a breakfast low in nutrition. However, the research suspects that the children's parents may be responsible for this relationship. Specifically, the better-educated parents probably encourage their children to eat better food and work harder in school compared to parents with less education. If the researcher is correct, this is an example of the_ O A. criterion problem O B. directionality problem O C.third-variable problem D. reversal problem Reset Selection 7,821 MAR etv A A O w 4 F7 F8 F9 F10 F11 F12 F2 & 3 4 5 7 9. %3D E Y

(Data source: Free publication available in many grocery stores. Data set available through the Statlib Data and Story.) Considering "Sugars" as the explanatory variable and "Rating" as the response variable generated the following regression line: Rating = 59.3-2.40 - Sugars. and the ANOVA table Source Regression Error Total SS df MS 8654.7 1 8654.7 102.35 6342.1 75 84.6 14996.8 76 F Questions: (a) Write down the simple linear regression model and its model assumption.

5) Please answer the question and show your work in the space provided. Medhavi suspects that there is a relationship between the number of text messages high school students send and their academic achievement. To explore this, she asks a random sample of 52 students at her school how many text messages they sent yesterday and what their grade point average (GPA) was during the most recent marking period. Her data are summarized in the scatter plot below. The least squares regression line is also shown. The equation of the least squares regression line is GPA=3.8-0.005(TextsSent).
