Answer:
95% confidence interval for the proportion of preschool children vaccinated in that suburb lie between (.5042 , .6958) 0r 50.42% to 69.58%
Step-by-step explanation:
Given -
A random sample of 100 preschool children in Camperdown revealed that only 60 had been vaccinated
Sample size ( n) = 100
Sample proportion = = 0.6
confidence interval = 95%
1 -.95 = .05
= = 1.96
95% confidence interval for the proportion of preschool children vaccinated in that suburb =
=
=
=
= (0.6 - .0958) , (0.6 + .0958)
= (.5042 , .6958)
