_D_e_t_a_i_l_s:

     Hicks (p.180, 1993) reports data from an experiment on methods for
     firing naval guns. Gunners of three different physiques (slight,
     average, and heavy) tested two firing methods. Both methods were
     tested twice by each of nine teams of three gunners with identical
     physique. The response was the number of rounds fired per minute.
