A linear regression model was fit to predict how much money a customer would spend at an online retailer (in $) based on the amount of time they were browsing the website (ranging between 1 and 100 minutes) along with the quadratic term for time. The coefficients table from a statistical application output is given below: Quadratic term Is there evidence of non-linearity in the relationship between spending and time spent at the website? No, since the quadratic term's coefficient is -0.008558, which is small in magnitude in comparison to the linear coefficient (1.598175). Yes, since the p-value for the quadratic term is 0.00282, which is less than 0.05. Yes, since the quadratic term's coefficient is -0.008558, which is non-zero. No, since the p-value for the linear term is < 2e-16, which is less than 0.05
