Question

Determine the point 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=0.480, upper bound=0.890, n=1200

The point estimate of the population proportion is__ (Round to the nearest thousandth as needed)

The margin error is__ (Round to the nearest thousandth as needed)

The number of individuals in the sample with specified characteristic is__ (Round to the nearest integer as needed)

Explanation / Answer

The point estimate of the population proportion is__ (0.890+0.480)/2 = 0.685

The margin error is  (0.890-0.480)/2 =0.205

The number of individuals in the sample with specified characteristic is 0.685*1200 = 822
