What are the hypotheses for testing to see if a correlation is statistically significant?
H0: r = ±1; H1: r≠ ± 1
H0: ρ = ±1 ; H1:ρ≠ ±1
H0: ρ = 0; H1:ρ=1
H0: r = 0; H1: r≠ 0
H0: ρ = 0; H1:ρ≠
The hypothesis to check that the correlation is statistically significant is:
E. H0: ρ = 0 ; H1:ρ ≠ 0
As here our null hypothesis is that the population correlation coefficient is 0 i.e. there is no significant relationship between the two variable and the alternative hypothesis is that the population correlation coefficient is ≠ 0 i.e. there is some relationship between the two variables and we carry out the test to identify if the relationship is significant to conclude that ρ ≠ 0 / correlation is statistically significant.
