Answer:
r = 0.9
Step-by-step explanation:
Correlation is denoted by r. r² is usually used to measure variation along the line as a fraction of the total variation.
We are told class attendance explained 81% of the variation in grade index among the students. Thus, for this regression, the variation is;
r² = 81%
Or r² = 0.81
Thus, the numerical value of the correlation r would be;
r = √0.81
r = 0.9
(4) -2 = 2 + v/4 (4)
-8 = 2 + v
-2 -2
V = -10
53,237-52,182= 1,055
My reasoning will be that I did subtraction
Alabama is larger
