What is the correlation coefficient for the following set of data? X Y 14 82 18 82 10 70 Group of answer choices -.86 .86 .92 -.92
Added by Shannon S.
Step 1
Given data: X: 14, 18, 10 Y: 82, 82, 70 Sum of X = 14 + 18 + 10 = 42 Sum of X squared = 14^2 + 18^2 + 10^2 = 196 + 324 + 100 = 620 Sum of Y = 82 + 82 + 70 = 234 Sum of Y squared = 82^2 + 82^2 + 70^2 = 6724 + 6724 + 4900 = 18348 Sum of XY = 14*82 + 18*82 + 10*70 = Show more…
