# Question

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
