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 following data to develop a regression model to predict the cost of a space project by the weight of the space object. Determine r2 and se.
Weight (tons) .... Cost ($ millions)
1.897 ........ $ 53.6
3.019 ........ 184.9
0.453 ......... 6.4
0.988 ......... 23.5
1.058 ........ 33.4
2.100 ......... 110.4
2.387 ......... 104.6
