A recent report claims that non-college graduates get married at an earlier age than college graduates. To support the claim, random samples of size 100 were selected from each group, and the mean age at the time of marriage was recorded. The mean and standard deviation of the non-college graduates were 22.5 years and 1.4 years respectively, while the mean and standard deviation of college graduates were 23 years and 1.8 years respectively. Test the hypothesis (the claim being made)...
