Question 1193965: a health study involves 1000 randomly selected deaths with 331 of them counted by heart disease. using the sample data construct a 99% confidence interval for the proportion of all deaths caused by heart disease Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! p hat=0.331
99% half-interval is z(0.995)*sqrt(p*(1-p)/n)
=2.576*sqrt(0.331*0.669/1000)
=0.0383
so the interval is (0.0293, 0.0369)
