Given: Maintenance expenses of 5 different cars for corresponding recorded miles.

Problem: If a car driven 50,000 miles, how much would be the maintenance cost?

Use Linear Regression equation to find the maintenance cost.

Solutions

Expert Solution

Ans ) $600.7683 (approx).

Explanation:

Mean = sum of all the values / total number of values

The formula for Linear Regression:

Therefore Linear Regression:

If a car has driven 50,000 miles, how much would be the maintenance cost?

Given X = 50000

ans.

So, For 50,000 miles Maintenance cost will be = $600.7683 (approx).
