Question
A researcher wants to estimate the proportion of depressed individuals taking a new anti-depressant drug who find relief. A random sample of 
275
 individuals who had been taking the drug is questioned; 
231
 of them found relief from depression. Based upon this, compute a 
95%
 confidence interval for the proportion of all depressed individuals taking the drug who find relief. Then find the lower limit and upper limit of the 
95%
 confidence interval.

Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.)

Lower limit:
 
Upper limit:
