Expert Solution
Step 1

Given : A ball is thrown into the air . The provided table shows the heights h (in feet) of the ball after t seconds . 

The following data are passed:

Time t Height h
0 5
2 31
4 33
6 11

The independent variable is , and the dependent variable is .

In order to compute the regression coefficients, the following table needs to be used :

  t h t*h t2 h2
  0 5 0 0 25
  2 31 62 4 961
  4 33 132 16 1089
  6 11 66 36 121
Sum = 12 80 260 56 2196
