8.)

The percent of the adolescents who were not in school had a desired pregnancy

=(No. of adolescents who were not in school had a desired pregnancy/ Total no. of adolescents who were not in school )*100

=(42/(42+27) )*100

= (42/69)*100

=60.9%

9.) What percent of the adolescents who were in school full time had a desired pregnancy?

The percent of the adolescents who were in school full time had a desired pregnancy

=(No. of adolescents who were in school full time had a desired pregnancy/ Total no. of adolescents who were in school full time )*100

=(49/(49+88) )*100

= (49/137)*100

=35.8%

10.) The study reports that the Chi-square test between pregnancy desire and being in school is significant. Interpret these results along with the answers you gave to questions 8 and 9 to draw a conclusion.

The chi-squared test between pregnancy desire and being in school is significant which means that no. of desired pregnancy depends on whether the given adolescent is in school or not in school.

Also, we observe that the percentage of desired pregnancy is 35.8% for adolescents in school full time, while it is 60.9% for adolescents not in school.

Thus, we can conclude that proportion of desired pregnancy is significantly higher for adolescents not in school than the adolescents in school full time.
