It corresponds to questions 4-6 in your Blackboard assignment. The questions are also listed here below:

4) Develop the estimated regression equation using all of the independent variables included in the data.

5) How much of the variation in the sample values of delay does this estimated regression equation explain?

6) Test the relationship between each independent variable and the dependent variable at the 0.05 level of significance.You will find one independent variable that is not significant.Which variable is this?
