So here we're told, according to a Nielsen survey, radio reaches 88% of children each week. Suppose we took weekly random samples of N equals 125 children from this population, and computed the proportion of children in each sample whom radio reaches. What will be the shape of the sampling distribution of the proportions of children the radio reaches? Once again, pause this video and see if you can figure it out. All right, well, let's just figure out what N and P are. Our sample size here, N, is equal to 125, and our population proportion of the proportion of children that are reached each week by radio is 88%. So P is 0.88.
