Ten engineering schools in a country were surveyed. The sample contained 250 electrical engineers, 80 being women; 150 chemical engineers, 30 being women. Compute a 99% confidence interval for the difference between the proportions of women in these two fields of engineering. Is there a significant difference between the two proportions?
