Determine whether the given correlation coefficient is statistically significant at the specified level of significance and sample size. r=−0. 599, α=0. 01, n=11

Respuesta :

Yes, the correlation coefficient is statistically significance

The precise metric used in a correlation analysis to quantify the strength of the linear relationship between two variables is the correlation coefficient. In a correlation report, the r stands for the coefficient.

Given,

Sample size, n = 11

Where ρ is the population correlation.

Then the number of degrees of freedom is, df = n-2 = 11-2 = 9

The corresponding critical correlation value re for a significance level of a 0.01, for a two-tailed test is た= 0.254

Here,

The null hypothesis,  = ρ - 0 is rejected

Suppose lr> re 0.254

Because on the sample correlation provided, we know that lrl = 0.599>=0.254.

Here, it is clear that the null hypothesis is rejected.
