Answer to Problem 34RE

Sum of the Squared Differences is 6 .

Explanation of Solution

Given information: Find the Sum of the Squared Differences for the set of data points

and the modal .

(-1,-4),(1,-3),(2,0)(4,5),(6,9).

  $y*=2.0x-12.$

Calculation:

Formula:

Evaluate $y*=2.0x-12.$ for each given value of x .Then find the difference y - $y^{\ast }$ using each value of y and the corresponding value of $y^{\ast }$ ,and square the difference.

  

Finally ,add the values in the last row to find the sum of the squared differences is 6 .
