Wait, is this a trick question? Are they trying to see if we're paying attention to the number of residuals? That's just cruel!

I'm with Yuonne on this one. The R-squared values for %Cu and Thickness seem to indicate they are the key drivers of heat flux. Time to brush up on my regression analysis!

Wow, this is a tough one! I'm going to have to think carefully about the relationships between the variables to nail this down.

B is definitely not correct. This is a linear regression, not a cubic one. And E is wrong too - the number of residuals should be equal to the number of data points.

I'm not sure about C and E, they don't seem relevant to the Regression Analysis.

C and D seem like the correct answers here. The regression plot shows that both %Cu and Thickness are significant predictors of heat flux.
