People in the aerospace industry believe the cost of a space project is a function of the mass of the major object being sent into space. Use the following data to develop a regression model to predict the cost of a space project by the mass of the space object. Determine r² and s_e.

Weight (tons)

Cost ($ millions)

1.897 $ 53.6

3.019 183.5

0.453 6.4

0.986 23.5

1.058 33.9

2.100 110.4

2.397 104.6
