PLEASE USE PREDICTION INTERVAL INSTEAD OF JUST USING EXCEL A sociologist is interested in predicting an income based on prior education level, with education level defined as the number of years of formal schooling. The following table shows the collected data. 15 29 144 37 20 23 13 7 9 27 1411 Income (in thousand dollar) Education (in years) 10 14 9 3 17 12 8 11 4 15 68 For the simple linear regression model in Question 6, the...

If you were to develop a linear regression equation that uses autonomy at work to predict job satisfaction, what would be the Y-Intercept (a) of the regression equation? Use the slope (b) obtained from the previous question to answer this question.

a Using the Excel’s Regression Tool, develop the estimated regression equation to show how income (y annual income in $1000s) is related to the independent variables education (level of education attained in number of years), age (Develop the dummy variable for the gender variable first. b. Use the t test to test whether each of the coefficients obtained in part (a) are significant at .05 level of significance. What are your conclusions? c. Use the F test to test...
