The following regression model has been computed based on a sample of twenty observations: = 34.2 + 19.3x.The first observations in the sample for y and x were 300 and 18,respectively.Given this,the residual value for the first observation is approximately 81.6.

Question

The following regression model has been computed based on a sample of twenty observations:  = 34.2 + 19.3x.The first observations in the sample for y and x were 300 and 18,respectively.Given this,the residual value for the first observation is approximately 81.6.

Quizplus · Accepted Answer

Using the formula for calculating residual value, we can plug in the given values for y, x, and the regression equation to get:

Residual = y - ŷ = 300 - (34.2 + 19.3*18) ≈ 81.6

Therefore, the answer is true.
