You are interested in determining the relationship between the income (Y), years of work experience (X1), years of education (X2), and gender (X3) (male or female) of the employees.

#### Question 0.Provide the Rcode below.

(a) Calculate the correlation coefficients

(i) between income and work

(ii) between income and educ

(b) Which variable (work or educ) has a stronger relationship with income?

**Answer**

(c) Plot income vs work (income to be displayed on y axis). Provide the Rcode below.

#### Question 1.Provide the Rcode below.

Regression to predict income by using the work experience.

(a) Obtain the simple regression model (M1) to predict the income by using the work experience of the employees. Provide the Rcode below.

(b) Display the summary output of the regression model (M1). Provide the Rcode below.

(c) What is the estimated regression equation?

**Answer**

(d) How much of the total variation in income is explained by this regression (SSR)?

**Answer**

(e) If you use regression prediction values as your estimate for the incomes of the employees, what would be the unexplained squared errors (SSE)?

**Answer**

(f) What percentage of the total variation in incomes is explained by thisregression (R_square)?

**Answer**

(g) Is the independent variable "work" experience significant in predicting the income of the employees at a significance level of 0.05?

**Answer**

(h) Construct 95% confidence interval estimate for the mean income of all employees with 20 years of work experience. Provide the Rcode below.

#### Question 2.Provide the Rcode below.

Regression to predict income by using the work experience, education, and gender.

(b) Display the summary output of the regression model (M3). Provide the Rcode below.

(c) What is the estimated regression equation?

**Answer**

(d) What does the coefficient of "gender" indicate?

**Answer**

(e) How much of the total variation is explained by this regression (SSR)?

**Answer**
