A recent article reported that a job awaits only one in three
new college graduates. The major reasons given were an
overabundance of college graduates and a weak economy. A survey of
200 recent graduates from your school revealed that 80 students had
jobs. At the .01 significance level, can we conclude that a
different proportion of students at your school have jobs? Use
critical value approach.

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)...
