Four significant variables? Looks like someone's been hitting the stats textbooks a little too hard. I prefer my regressions simple and easy to understand.

I believe option C is incorrect because the R-squared value is not 98+%, it is actually 50.8% as mentioned in option A.

Hmm, 98+%? Now we're talking! This model must be as accurate as a Swiss watch. I'll take it!

Wait, 50.8%? That's barely passing the class! I need at least a solid 85% to impress my boss.

I agree with Carri, because the R-squared value is 0.508 which means 50.8% of the variation in the dependent variable is explained by the independent variable.
