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
