Question

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 se.

Weight (tons) Cost ($ millions)

1.897 $ 53.6

3.019 184.4

0.453 6.4

0.978 23.5

1.058 32.6

2.100 110.4

2.404 104.6

*(Do not round the intermediate values. Round your answers to 4 decimal places.) **(Round the intermediate values to 4 decimal places. Round your answer to 3 decimal places.)

ŷ = __________ + __________ * x

r2 =_________________ **

se = ________________**
