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 characteristic, x, for the sample size provided.

Lower bound= 0.323, upper bound= 0.667, n= 1200

The point estimate of the population proportion is:

Solution

Note that

p^ (point estimate) = [lower bound + upper bound]/2 = 0.495 [answer]

E (margin of error) = [upper bound - lower bound]/2 = 0.172 [answer]

x (individuals with specified characteristic)= p^ n = 594 [answer]
