Question 1045565: An online site presented this question, �Would the recent norovirus outbreak deter you from taking a cruise?� Among the 34,319 people who responded, 64% answered �yes�. Use the sample data to construct a 90% confidence interval estimate for the proportion of the population of all people who would respond �yes� to that question. __ < p < __ (round to three decimal places as needed)

the interval is z+/- sqrt {(p)(1-p)/n}=1.645+/-sqrt(0.64)(0.36)/34319; the sqrt term=0.00259
z*SE=0.004
(0.636,0.644) or 0.636
