Use empirical rule to establish interval for observations

Reference no: EM13138811

A sample of 25 undergraduates reported the following dollar amounts of entertainment expenses last year:

690 686 714 738 682 751 724 713 763 703 703 711 771
719 691 715 752 717 750 703 720 772 743 739 744

Use the Empirical Rule to establish an interval which includes about 95 percent of the observations.
