10-3

In 1994​, a reproductive clinic reported 42 live births to 151 women under the age of​ 38, but only 9 live births for 84 clients aged 38 and older. Is there evidence of a difference in the effectiveness of the​ clinic's methods for older​ women?

​a) Test an appropriate hypothesis and state your conclusion.​ (Use the pooled sample proportion when checking the​ success/failure condition.)

​b) If you concluded there was a​ difference, estimate that difference with a 99​% confidence interval and interpret your interval in context.
