Cubic Regression? That seems off to me.

I vaguely remember that the number of residuals is usually related to the sample size, but I can't remember if it's specifically 26 in this case.

I practiced a similar question where we had to identify the type of regression, and I feel like this might be cubic regression, but I could be wrong.

I think option C sounds familiar; we talked about how certain variables can explain variance in heat flux, but I can't recall the exact percentages.

I remember discussing multiple linear regression in class, but I'm not sure if this one fits that definition.

Ah, I think I've got it. The "L" is likely referring to the length or distance of the optical transmission. That makes the most sense given the options provided.

Okay, I've got this! The Safe Action button is Option C. I recognize that icon from using the Maya tools before. Feeling confident about this one.

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!

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.
