Determine the point estimate of the population proportion th

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 characteristics, x for the sample size provided lower bound = 0.118, upper bound = .481, n = 1670

Solution

Confidence interval given = (0.118, 0.481)

n = 1670

Point estimate for population proportion = Mid point of the interval

= 0.2995

---------------------------------------------

Margin of error = 0.2995-lower bound

= 0.1815
