Question 16

Sunil is testing, at the 5% significance level, whether there is any correlation between two variables in a population whose correlation coefficient is $ρ\rho$ .

Identify the correct alternative hypothesis for Sunil's test.

Tick one box.

$H1:ρ=0H_1: \rho = 0$

$H1:ρ>0H_1: \rho > 0$

$H1:ρ<0H_1: \rho < 0$

$H1:ρ≠0H_1: \rho \neq 0$
