Determine the point estimate of the population proportion, the margin of error for the following confidence interval, and the number of individuals in the sample with the specified characteristic, x, for the sample size provided.
Lower
boundequals=0.5350.535,
upper
boundequals=0.8850.885,
nequals=1000
Solution :
Point estimate = = (Lower confidence interval + Upper confidence interval ) / 2
Point estimate = = (0.535+0.885) / 2=0.71
Margin of error = E = Upper confidence interval - = 0.885-0.71=0.175
The number of individuals in the sample with the specified characteristic is ,
x = * n = 0.71*1000
The number of individuals = 710
