Ten engineering schools in a country were surveyed. The sample contained 225 electrical engineers, 90 being women; 175 chemical engineers, 20 being women. Compute a 90% 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?

C Let p, be the population proportion of electrical engineers that are women in the schools that were surveyed and let p₂ be the population proportion of chemical engineers that are women in the schools that were surveyed. The 90% confidence interval is <P₁-P₂ <- (Round to three decimal places as needed.)
