Question 1119794: A government official is in charge of allocating social programs throughout the city of Vancouver. He will decide where these social outreach programs should be located based on the percentage of residents living below the poverty line in each region of the city. He takes a simple random sample of 128 people living in Gastown and finds that 24 have an annual income that is below the poverty line.
Use the sample data to compute a 95% confidence interval for the true proportion of Gastown residents living below the poverty line.

point estimate is 24/128 or 0.1875
95% CI has interval 1.96*sqrt (0.1875*0.8125)/128
This is 0.0676
(0.1199, 0.2551) is the interval
