(A) The mortality function for the two balloon types shows the cumulative probability that a balloon will burst as a function of the time for which it was inflated. (B) The optimality function for the two balloon types shows the cumulative number of points earned if participants stopped inflating the balloons at specific inflation durations. The greatest number of points would be earned if all small balloons were inflated for 2,220 msec and all large balloons were inflated for 3,720 msec.
