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 8 to 12 , beginning ice-skating class was picked. In that class were 66 girls and 14 boys. Suppose that we are interested in the true proportion of girls, ages 8 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 a 96% confidence interval for the true proportion of girls in the ages 8 to 12 beginning 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.
