Rural Area Small Urban Area Large Urban Area
35 28 24
30 24 28
36 25 26
38 30 30
29 32 34
a. At the .05 level, can you conclude there is a difference in the three mean scores?
b. If the null hypothesis is rejected, can you state that the mean score of those with a rural background is different from the score of those with a large-city background?
