Note. Table shows mean enrollment likelihood, benefits, and costs by number of plans and number of numeracy questions correct. Standard deviations are shown in squared brackets, with asterics indicating if the mean is statistically different from the mean within the same number of plans and 0 correct. In the last two columns, data is pooled across choice set size (all choice set sizes are included) and tests show if the mean is different by numeracy questions correct from the mean with 0 correct.

Significance levels shown are ** p<0.01,

^*p<0.05.
