After Bonferroni correction for 12 tests, the p_critical for each of these statistical tests was 0.0042. Thus, all 12 negative linear relationships were found to be significant (i.e. their slopes were significantly less than 0). Means and standard deviations of the goodness-of-fit (R²) data are also provided.
