Project Instructions:
- Every student suppose to attempt his or her project independently
- Write your Project in Proper way, First Question, then regression code, results and interpretations of both questions respectively.

Question 1: Simple regression model.
From table select one dependent and one independent variable.
a. Identify the regression line.
b. Identify and interpret the y-intercept and the slope of the linear equation in (a)
c. Describe the apparent relationship between two variables under consideration.
d. Graph a scatterplot for the data.
e. Compute coefficient of determination, r2.
f. Determine the percentage of variation in the observed values of the response variable explained by the regression, interpret your answer.
Note: Do all steps manually as well as use R-codes. Then compare the results.

Question 2: Multiple Regression Model.
Use one dependent and other independent variables and perform the following
a) Identify the response variable and explanatory variables
b) Graph the relationship between the response variable and each of explanatory variables
c) Determine the regression equation and interpret the coefficients as well regression equation
Note: Do all stepswith the help of R-Codes
