Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p.

Thank you for the opportunity to help you with your question!

the estimate of p is p= 68/110= 0.618

std = sqrt(0.618*(1-0.618)/110) = 0.0463

for 88% confidence of interval k = 1.555

thus CI is

-1.555*0.0463<mu-0.618<1.555*0.0463

0.546 <mu<0.690
