Statistics

The proportion of drivers who use seat belts depends on things like age, gender, ethnicity, and local law.

Give a 95% confidence interval for the proportion of all female hispanic drivers in Boston who wear seat belts. Does this data give good reason to conclude that more than half of hispanic female drivers in Boston wear seat belts?
