1. 1. Guided Example 03-62
2. A sample of 25 undergraduates reported the following dollar amounts of entertainment expenses last year:

   684	710	688	711	722	698	723	743	738	722	696	721	685
   763	681	731	736	771	693	701	737	717	752	710	697

   1. Find the mean, median, and mode of this information.
   2. What are the range and standard deviation?
   3. Use the Empirical Rule to establish an interval which includes about 95% of the observations.
