Question

X Y 74 45 72 12 y 0.5757x-1.1141 60 69 42 r 0.509963 50 65 50 40 62 42 30 58 40 57 30 20 55 33 10 50 35 47 26 0 20 40 60 80 45 15 38 15

At a significance level of a = 0.05, is there enough evidence to suggest that the variables are correlated? If YES, Predict the Y-value for X = 45 and Predict the X-value for Y = 10.

Answer 1

Solution :

Given that,

$\alpha$ = 0.05

r = 0.509963

n = 13

P-value = 0.075

P-value > $\alpha$

There is not enough evidence to suggest that the variables are correlated .
