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 s_e.

Weight (tons)	Cost ($ millions)
1.897	$ 53.6
3.019	183.6
0.453	6.4
0.960	23.5
1.058	32.6
2.100	110.4
2.370	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 = ( ) **

Please Fill in the ( ) blanks

Answer 1

The statistical software output for this problem is :

= -38.3699 + 66.0614 x

r ² = 0.909

S _e = 20.636
