Question

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 bound equals=0.463​,

upper bound equals=0.697​,

nequals=1500

Answer 1

Given that

Lower bound =0.463​,

upper bound =0.697​,

n=1500

Calculate the point estimate Point EstimateUpper Bound Lower Bound Point Estimate 0.6490.463 Point Estimate : 1.112 Point Estimate 0.556

Margin of Error Upper Bound - Point Estimate Margin of Error 0.649-0.556 Margin of Error 0.093

Since the confidence level is not given hence it is difficult to calculated sample size .
