Histograms of p(F_test) values of fitting a straight line to the RV–CRX, RV–dLW, and RV– log L_Hα∕L_bol scatter plots for the stars in Table 1. The solid black curve represents a uniform distribution between 0 and 1 scaled so that its integral is equal the number of RV-loud stars. The dashed vertical line is the critical p-value for suggestive evidence (0.05), and the dash-dotted vertical line is the critical p-value for significant evidence (0.005). The histogram is truncated at 5 × 10⁻⁷. Lower p-values are contained in the left-most column.
