The constant variance condition does not appear to be met because there is an obvious funnel pattern present in the residual plot. The normality condition does not appear to be met because there are significantly more residuals greater than zero than there are residuals less than zero. The conditions of linearity, normality, and constant variance all appear to be met since there is no obvious pattern in t residual plot. Open

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? Residuals 5 -5
