BUAD 310 Minitab Project 6 1. a.) The correlation is bigger than -1 but still negative. I get a correlation of -0.934 b.) E (Y) = E (2-3x + E) = E (2) + E (-3x) + E (e) = 2 – 3 E(x) + E (e) = 2-3(0) + 0 = 2 c.) The correlation between X and Y would be stronger, making the points closer to the line d.) The correlation would be -1 e.) The correlation would be close to 0

Unformatted text preview: If the correlation = 0 it doesnt mean x & y are independent If correlation = 0 and x & y are independent then x and y must be from a normal distribution 2. a.) 10 2 (2-3x+e) = 6 + 6x 2e Correlation = close to -1 b.) correlation = 1 3.) a.) The correlation between e & Z should be close to 0 b.) The new correlation will be close to 1 c.) Make the largest number even larger than 15...
