(b) Repeat PHStat –> Multiple-Sample Test –> One-Way ANOVA (a) Open a new file and copy your data into this new file PHStat REGRESSION procedure, when CIE & PIE is selected, sometimes fails to work. (k) Now, compare your conclusion in (j) above with the conclusion you had in your answer (j) Based on the hypothesis testing result of (i) above, does the GENDER have a significantĮffect on the INCOME of the employees in your occupational group? What does it mean to reject the Null hypothesis (b3=0) in this case? (i) In testing Ho that b3=0 against the two sided alternative, should the Null hypothesisīe rejected or accepted at a sinficance level of 0.05? With 20 years WORK experience and 14 years of EDUCation. (h) Construct 95% confidence interval for the mean INCOME of the MALE employees Of WORK, EDUCATION, and GENDER (r2Y.123)? (g) What percentage of the total variation in employee INCOMES is explained by the years (f) How much of the total variation is explained by the years of WORK, EDUCation, and What would be the squared errors – error sum of squares (SSE)? (e) If you use multiple regression prediction values as your estimate for employee INCOMES, (d) If you had used the average INCOME as your estimate, what would be the total sum of (c) Using the estimated multiple regression equation, calculate the predicted INCOME of aįEMALE employee with 20 years of WORK experience and 14 years of EDUCation. (b) State the meaning of the slope b3 for the GENDER of the employees. Regression line Y = b0 + b1X1 + b2X2 + b3X3 (a) Using the method of least squares, determine the equation for the estimated X3=GENDER) as the independent variables to predict the INCOME of the employees Suppose you wanted to use all three variables (X1= years of WORK, X2= EDUCation and You can use PHStat output to answer these questions. Occupational group as part of homework 1). (You will be using the file that you have created for your The years of WORK (X1), years of EDUCation (X2) and GENDER (X3) (male or female) for theĮmployees in your occupational group.
You are interested in determining the relationship between the employee INCOME (Y), and of Note: The answers to all questions should be provided (written down).
