Answer:
The predicted price of ticket if driving at 85 mph is $117.538
Explanation:
The data points are;
(65, 25 )
(68, 37 )
(72, 55 )
(88, 120)
(76, 82 )
(90, 150)
(74, 64)
The Linear Regression Equation for the given data is; y = 4.671·x - 279.497
Therefore, the price of a ticket if driving at 85 mph is given as follows;
y = 4.671 × 85 - 279.497 = 117.538
The predicted price of ticket if driving at 85 mph = $117.538.
