Bold Values represent correlations statistically significant at the 0.05 level (2-tailed).

The correlation between the variables is statistically significant in a 2-tailed test at the 0.05 level (*) or at the 0.01 level (**).

The correlation between the variables is statistically significant in a 2-tailed test at the 0.05 level only in the high-ETS subset (N=9).
