Consider the following regression analysis for predicting sales per week from intelligence and extroversion scores:
The regression equation is
Sales/Week = 994 + 8.22 Intelligence + 49.7 Extroversion

Which of the predictors (if any) do not appear to be linearly correlated with sales per week?
◦
Both predictors are significant because thep-value from the global utility test is essentially zero.
◦
Neither of the predictors is significant because the R-Sq value is low (32.56%).
◦
Intelligence does not appear to be linearly correlated with sales per week because itsp-value is 0.257.
◦
Extroversion does not appear to be linearly correlated with sales per week because itsp-value is 0.021.
