Hi @David Harper CFA FRM
Love the videos.
Am on video Stock & Watson 4 &5.
Your first question, find small r.
I had it 98% of the way.
One thing threw me off: you mention in the question that the TSS = 90.625 dollars ^2
--- what does the ^2 part mean in the TSS? Do I have to square the 90.625 in the denominator to calculate the R^2? If not, why mention the ^2 at all?
Thanks
Again -- love the videos. Have added so much colour and quality to my studying.
