The assumptions that must be true in order to use a linear regression model are:
1. Existence: For any fixed variable X.Y is a random variable with a specific probability
distribution that has a finite mean and finite variance that depend on X.
2. Indepen

The assumption required to carry out this test statistic are:

distribution that has a finite mean and finite variance that depend on X.
2. Independence: The y-values
