    How did you prove the binomial part a? i tried expanding both and then dividing them, but could only get the first two terms. Wasn't sure how to do it. Also the vectors part B was odd. Besides from that all my answers are the same as Harolds, so i'll assume theyre correct

    i'm not too sure, since you essentially affected all parts of the question. Your pmcc will come out different as will your regression line.

    sd is unaffected since it's not affected by addition or subtraction.
