April 08 exam question 8 Can anyone help me out? I'm wondering how to calculate the beta's for part 2 of this question from the confidence intervals given? Hi, they've used the formula for confidence intervals. That is: So taking Violin for example B1 + z*SE(B1) = 0.19 B1 - z*SE(B1) = -0.05 Addind these two together (solving by simultaneously equations) this becomes 2B1 = 0.14 and finally B1 = 0.07 A similar method has been used to calculate B for the others. Hope this helps.
