Suppose you are estimating a wage regression, where salary is the dependentvariable and age, years of education and a dummy variable for male are yourindependent variables. You are interested in measuring how salary differs betweenthose who have at least a college education with those who have less than a collegeeducation. If a person is considered as having a college education when she hasmore than 12 years of education, how can you measure the difference in salarybetween college and non-college educated individuals?Select one:a. Multiply coefficient for years of education in original regression by 12O b. Re-estimate model replacing years of education with a dummy variable forcollegec. Re-estimate model replacing years of education with a dummy variable forcollege and one for no collegeO d. Re-estimate model interacting years of education with a dummy variable forcollegee. Calculate the difference in predicted salary between an individual with 14years of education and one with 7 years of education

Given that, for estimating a wage regression, where salary is the dependent variable and age, years…

What is regression models?
Bill wants to explore factors affecting work stress. He would like to examine the relationship between age, number of years at the workplace, perceived social support, and work stress. He collects data on the variables from 100 employees (males and females) working in banks. Conduct a multiple regression analysis to answer the following questions: What is the relationship of age, number of years, and social support with work stress? Is the regression significant? If yes, what does it indicate? What is the regression equation for all the predictors? Write a results section based on your analysis that answers the research question. * last person got this wrong*
Suppose you a manager for a local car dealership, and you want to use a linear regression model to predict the price of a used car. You decide to use four predictor variables - "Age' (how long the car has been in use since it was produced), "Dents" (the number of visible dents on the outside of the car), "Accidents" (the number of accidents the car has been in), and "mpg" (the fuel efficiency of the car, measured in miles per gallon). Your dataset contains this information for the past 120 cars sold at your dealership. Using this model, your analysis finds an R² of 37%. What is the F statistic of your analysis? Note: 1- Only round your final answer. Round your final answer to two decimal places.
I am having difficulties understanding how to compare two variables using the Regression Analysis to see if there is a correlation. Will you provide some help? Thanks.
You are interested in whether there are gender differences in voting behaviour using the European Social Survey. Youestimate a regression model with being a woman as the single explanatory variable. Clearly write down the regression model.
You run a regression of homework grades on hours spent studying, and get the following regression equation: Grade = 94 – 6.2 * Hours_Spent_Studying + error What is your takeaway from this regression? Group of answer choices a) Studying is bad, and causes worse grades. b) Students don’t know how to study very well. c) A few outliers are skewing the results. d) Students who are less confident study more, but still do worse. There is an omitted variable skewing the results.
Describe a hypothetical study for which multiple regression with more than two predictor variables would be an appropriate analysis. Your description should include one dependent variable and three or more predictors.
A rural state wants to encourage high school graduates to continue their education and attend college. The state collected information on a random sample of high school seniors from across the state 7 years ago and is now observing how many years of education they completed. They believe students decide to achieve more education when they are more capable, have easier access to college education, and the opportunity cost of attending are lower. To explore the factors that affect the years of education completed they have used multiple regression to estimate the years of completed education as a function of: Unemployment rate - the unemployment rate in the county (3.9 – 16.8) County Hr Wage - average starting hourly manufacturing wage in the county Test - student score on college admission test (0 to 100 scale) Dist to college - Distance to near college (measured in 100’s of miles) Tuition - Tuition charged at nearest state university (measured in $1000s)…

Below is some of the regression output from a regression of the amount various customers paid for a new car (expressed in dollars) versus the age of the customer (expressed in years), the number of previous cars the customer had purchased from the dealership in the past, a dummy variable indicating the gender of the customer (=1 for a Man and = 0 for a woman), and an interactive term the multiplies the age of the customer with the gender dummy variable.
