32. People in the aerospace industry believe the cost of a space project is a function of the weight of the major object being sent into space. Use the regression output and scatterplot to answer the following questions: 200 Coefficients 150 Intercept -39.01 100 X Variable 1 66.36 Cost ($ millions) 50 0 0.5 1 1.5 2 2.5 3 3.5 Weight (tons) a. Give and interpret the slope of the prediction equation. (3 points) b. Use the prediction equation to predict the cost (in millions of $) of a space project in which the weight of the major object being sent into space is 2 tons (2 points) c. Can you use the prediction equation to predict the cost (in millions of $) of a space project in which the weight of the major object being sent into space is 6 tons? Explain your answer. (2 points). d. Based on the above information for this problem (and no other information) can we say that the relationship between weight of the major object being sent into space directly causes cost of the space project to increase? In other words - does correlation imply causation?(2 points)
