5. There is some indication in medical literature that doctors may have become more aggressive in
inducing labor or doing preterm cesarean sections when a woman is carrying twins. Records at a large hospital show that of the 43 sets of twins born in 1990, 20 were delivered before the 37th week of pregnancy. In 2000, 26 of 48 sets of twins were born preterm. Does this indicate an increase in the incidence of early births of twins? Test an appropriate hypothesis and state your conclusion. Calculate and interpret a 90% confidence interval.
