Respuesta :

Using linear regression, the estimate for the average cost per student at an enrollment of 750 students is of $373.

How to find the equation of linear regression using a calculator?

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points are given as follows:

(170, 539), (250, 482), (450, 421), (650, 415).

Inserting these points into the calculator, the function is:

y = -0.24733x + 558.23703.

When x = 750:

y = -0.24733(750) + 558.23703 = 373.

The estimate for the average cost per student at an enrollment of 750 students is of $373.
