4) Conduct a hypothesis test on H0: slope = 0; Ha: slope positive or negative (your hypothesis from part 2). Using α = 0.05, is there a significant linear relationship between x and y (paste your output to support your answer)? What is the linear model (y = mx + b, fill in the numbers for m and b)? In the context of the problem, what is the interpretation of the slope, m?
