A researcher obtains a Pearson correlation of r = 0.60 for a sample of n = 6 pairs of X and Y scores.If the researcher tests the significance of the correlation,what value will be obtained for the t statistic?
A)0.6/0.16 = 3.75
B)0.6/0.4 = 1.50
C)0/6/0.8 = 0.77
D)0.6/1.0 = 0.6

To calculate the t statistic for a correlation coefficient, we use the formula t = r*sqrt(n-2)/sqrt(1-r^2). Substituting in the values, we get t = 0.60*sqrt(6-2)/sqrt(1-0.60^2) = 1.50. Therefore, the correct option is B.
