Question
1.
A computer manager needs to know how efficiency of her new computer program depends on the size of incoming data. Efficiency
will be measured by the number of processed requests per hour. The response variable here is the number of processed requests Y
and the explanatory variable is the data size X.
The estimated regression equation for this relationship based on a sample of size 11 is y
70.16 3.39x.
A plot of the residuals for this regression equation is included below. Which of the following statements regarding the linear
regression conditions for inference is correct?
