Question

1. (2 point) Calculate the correlation coefficient r. This table is intended to help you set up the calculation for the correlation coefficient by hand. Please show work. I would recommend you verify the that you got the correct answer by using your TI-84 Column A: The x deviations from the mean: (x-x) Column B: The y deviations from the mean: GViT YI Multiply the values in the Columns A and B. The product of the deviations. (-4.15)(4.05)-16.808 3.5-7.65-4.15 12.4-8.35 = 4.05 Sum the above rows for multiply the summed value last cell above) y) by (n-1)-Sx 5)y 1(xi-i) y Now to finish the calculation for r Show work here: by n-1-

Explanation / Answer

We are allowed to do 1 question at a time. Post again for second question.

2) a) An explanatory variable is a type of independentvariable. The two terms are often used interchangeably. But there is a subtle difference between the two.
