Extracted text: 1. Data science is one of the fastest growing business functions, which is reflected in salaries for data science jobs. Because the work is done almost entirely using computers, such jobs can usually be performed remotely. The Covid pandemic has made remote work more common. To determine how remote work affects salaries, a dataset with a sample of 169 data science jobs can be found below. The dataset includes the following variables: Job Title Salary (US $) - annual salary in US dollars Large Company – dummy variable indicating whether the company has more than 250 employees (1=yes, 0=no) US Company – dummy variable indicating whether the company is US-based (1=yes, 0=no) Remote – dummy variable indicating whether the job is remote (1=yes, 0=no) a) Using the below", estimate a simple linear regression to predict Salary using only Remote as an independent variable. How well does the model fit the dependent variable? Report the relevant value and briefly explain. b) What is the estimated slope coefficient for the model estimated in part (a)? Interpret that slope coefficient. Is there a linear relationship between the independent and dependent variables at a= .05? Report the relevant test statistic and p-value for that test statistic. c) Now estimate a multiple linear regression to predict Salary using all available independent variables: Large Company, US Company, and Remote (do not include Job Title). Write the estimated regression equation. d) Is the model estimated in part (c) statistically significant at the a = .05 level? Write the null and alternative hypotheses for this test, the appropriate test statistic, the p-value for that test statistic, as well as your conclusion. e) Which independent variables (if any) in the model estimated in part (c) are related to the dependent variable Salary at the a = .05 level, given the other independent variables in the model? Include relevant values from the data output to support your conclusions.
