aleksley [76]

So to set up the equation we have: 4M4+M=127
28M=12(4+M)
28M=48+12M
28K−12M=48
(28−12)M=48

Correlation 0.9199

H0: r=correlatin =0

Ha: r ≠0

(two tailed test)

r difference = 0.9199

t = $r*\sqrt{(n-2)/(1-r^2)} \\=4.063$

p value < 0.0001

Since p <0.05 we reject null hypothesis

There is a significant linear correlation between the two variables.
