Based on the regression output, which of the following is a valid justification for why the coefficients on max and min resolution are negative?

If alcohol content decreases by 5 units, conditional on all other variables remaining constant, what is the impact on the wine quality? Use alpha=.10.

Is the coefficient on generalmills statistically significant at the .05 level?

Picture perfect cameras Peter Parker, whose day job is taking pictures for a local newspaper, wants to purchase a new camera to improve his photo quality. Beforehand, Peter wants to understand how the max resolution (Max.resolution, in thousands of pixels) and the min resolution (Min.resolution, in thousands of pixels) of the camera impact the price (Price, in dollars). He wants to understand more complex relationships with price so he creates an interaction variable Interact.max.min.resolution. He then runs a regression of camera Price on Max.resolution, Min.resolution, and Interact.max.min.resolution, with the following R output:
