14.33 A random sample of 80 owners of videocassette recorders was taken. Each sample member was asked to assess the amounts of time in a month spent watching material he or she had recorded from television broadcasts and watching purchased or rented commercially recorded tapes. The 80 differences in times spent were then calculated and their absolute values ranked. The smaller of the rank sums, for material recorded from television, was 1,502. Discuss the implications of this sample result.
