In a social study, a random sample of 150 teachers were selected and an independent random sample
of 100 nurses were selected. Each person was asked if they currently have a second job. The results
showed that 48 of the 150 teachers and 21 of the 100 nurses had a second job. Construct and interpret
a 95% confidence interval for the difference in the proportion of all teachers and nurses that have a
second job.
