##### Solution Preview

The two statistical Methods discussed are:

1. Regression Analysis

2. Chi-Square Test

In regression analysis, we develop an estimating equation - that is a mathematical formula that relates the known variables to the unknown variable. The simple regression analysis is done to test the linear relationship between the dependent variables and independent variables. Thus, if X is independent variable and Y is independent variable, we are going to test the model:

Y = a + bX

The goals for the regression is to estimate the values of a and b. While formulating the hypothesis, we have to keep ...
