The regression equation that shows the population P(x) is given as follows:
P(x) = 3.02x + 7.81.
With the model, the prediction for the population in year 88 is of 273.
<h3>How to find the equation of linear regression using a calculator?</h3>
To find the equation, we need to insert the points (x,y) in the calculator.
For this problem, the points are given as follows:
(0,7), (5,17), (23,84), (31, 107), (45, 143), (60, 182), (68, 217), (79, 249).
Inserting these points in the calculator, the equation is given by:
P(x) = 3.02x + 7.81.
The prediction for the population in year 88 is given by:
P(88) = 3.02(88) + 7.81 = 273.
