A researcher wished to determine if there was a difference in the college aptitude examination scores of traditional and nontraditional undergraduate students. The researcher selected p = .05 as the level for rejecting the null hypothesis. The researcher obtained a mean score of 52 for nontraditional students and a mean score of 40 for the traditional students. Statistical analysis indicated that the difference in means was significant at the .05 level. How would the statistical significance be interpreted?
a. Traditional and nontraditional students are drawn from the same population in terms of college aptitude.
b. There are 5 chances in 100 that the two groups were drawn from different populations in terms of their college aptitude.
c. There are 5 chances in 100 that the two groups were drawn from the same population in terms of their college aptitude.
d. For every nontraditional student, there are 5 chances in 100 that she/he will score higher than a traditional student.
