A pearson correlation is computed for a sample of n 18 pair

A pearson correlation is computed for a sample of n = 18 pairs of X and Y values. What correlations are statistically significant with a = .05, two tails? Correlations be between 0.468 and -0.468 Correlations greater than or equal to 0.468 and correlation less than or equal to -0.468 Correlations between 0.456 and -0.456 Correlations greater than or equal to 0.456 and correlation less than or equal to -0.456

Solution

df=N-2=18-2=16

so from the table critical values are 0.468 and -0.468

so 3. correlations greater than or equal to 0.468 and correlation less than or equal to
