A researcher wants to estimate the proportion of depressed individuals taking a new anti-depressant drug who find relief. A random sample of 225 individua who had been taking the drug is questioned; 177 of them found relief from depression. Based upon this, compute a 95% confidence interval for the proport 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.)
