the acceleration due to gravity at an altitude y above the surface of the earth is given by:
y(m) g(m/s^2)
0 9.8100
30,000 9.7487
60,000 9.6879
90,000 9.6278
120,000 9.5682
a.) Do a regression analysis to find the best fit for the data.
b.) what is the coefficient of determination.
c.) what is the significance of coefficient of determination with respect to your regression analysis?
d.) what is the best estimate of gravity at y= 55,000 m?
