loanamt = Amount of Mortgage Loan Application (in \$1000)

income = Applicant’s Annual Income (in \$1000)

hprice = House Price to buy (in \$1000)

6) t test for the coefficient of income (Ho: B1  = 0 )

7) F statistics and perform the test for the model

8) Variance of et

9) According to the model what are the predicted loan amount if applicants have annual income of \$50,000, \$100,000, and \$200,000 and their confidence intervals?

10) List and explain the assumptions you made for a simple regression model

6).

The null hypothesis:

The slope coefficient of income is not significant.

Alternative hypothesis:

The slope coefficient of income is not significant.
