During class, Bobby sometimes throws his pen (at least 1 foot from his current location). For eight school days, staff took data on Bobby’s pen throwing.  Across the eight days, Bobby threw his pen 26 times. On average, 6 minutes passed between pen throws. The longest amount of time observed to pass between pen throws was 11 minutes. The shortest amount of time observed to pass between pen throws was 2 minutes. Based on these data, how often should school staff wait between deliveries of the reinforcer for pen throwing?
