x y

10 93

15 171

20 204

20 156

35 261

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.
