The Ice Chalet offers dozens of different beginning iceskating classes. All of the class names are put into a bucket. The 5 P.M., Monday night, ages 8to 12, beginning ice-skating class was picked. In that class were 66girls and14 boys. Suppose that we are interested in the true proportion of boys, ages8 to 12, in all beginning ice-skating classes at the Ice Chalet. Assume that the children in the selected class are a random sample of the population.

We want to construct a92%confidence interval for the true proportion of boys in the ages8to12beginning ice-skating classes at the Ice Chalet. Select the correct graph of the normal density curve, with properly labeled areas, upper and lower limits of the confidence interval, and the sample proportion.
