Percentage of persons completing 4 years of college:

23 26 30 34 26 25 23 22 31 22

24 38 33 27 27 34 24 24 24 21

22 24 28 29 25 24 17 36 28 28

27 28 24 21 24 37 23 19 25 21

33 30 25 26 25 24 25 31 15 26

You learn that the data is actually a sample from the U.S. population where 1000 people were surveyed from each state and the percentage reflects the percentage of the sample who completed 4 years of college (bachelor's degree).

Another researcher claims that the national average is 32 with a standard deviation of 5.2. At an ? = .01, does your sample differ from that stated national average? Record and explain the result. Speculate on the results.
