At a used dealership, let X be an independent variablerepresenting the age in years of a motorcycle and Y be thedependent variable representing the selling price of usedmotorcycle. The data is now given to you. X = {5, 10, 12, 14, 15} Y= {500, 400, 300, 200, 100}
1) What is the value for S^2?
2) What is the value for s?
3) Construct a 95% confidence interval for B1. what is the upperbound and lower bound?
4) does the data provide sufficient evidence to indicate that Xcontributes to the prediction of Y?
