Question 2 5 pts Which of the following is true about the p-values displayed in the output from Excel for a regression model? O We should ALWAYS evaluate the p-value at a 0.05 level of significance. O p-values are only considered useful when the R-square value is greater than 1. O p-values are only statistically significant if they are estimated from a non-linear model. O If a p-value is found to be statistically significant, this does NOT guarantee that it will also be practically significant
