Question 1202135
Confidence Interval for a Population ProportionConfidence Interval for a Population Proportion

p hat is 243/368=0.6603
the half interval is z(0.995)*sqrt (p hat*(1- phat)/n)
half-interval Is 2.576*0.0247=00636
interval is (0.597, 0.724) and you can use that to make the tri-linear inequality.
