Use a hypothises test to determine if the proportions are statistically different.

A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180

high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than the

proportion of elementary teachers who were single? Use ΅ = 0.01.
