In 2004 the estimated average housing space per person (in square feet) was 474 in country A but only 456 in country B. Suppose a team of economists and sociologists from an organization plans to reestimate the difference in the mean housing space per person for workers in country A and country B using a 99% confidence interval with a sampling error of 5 square feet. Find the sample sizes required to obtain such an estimate. Assume equal standard deviations of = 64. The sample sizes should be n, =n2 = 3. (Round up to the nearest integer as needed.)

Statistic

In 2004 the estimated average housing space per person (in square feet) was 474 in country A but only 456 in country B. Suppose a team of economists and sociologists from an organization plans to reestimate the difference in the mean housing space per person for workers in country A and country B using a 99% confidence interval with a sampling error of 5 square feet. Find the sample sizes required to obtain such an estimate. Assume equal standard deviations of 2. 2 = 64. The sample sizes should be n, =n2 =3 (Round up to the nearest integer as needed.)
