Chapter 8, Problem 85P

Use the following information to answer the next 16 exercises. The Ice Chalet offers dozens of different beginning ice- skating 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 the class were 6.1 girls and 16 boys. Suppose that we are Interested in the true proportion of gixls, 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.

State the estimated distribution of P’. Construct a 92°o Confidence Interal for the true proportion of girls in the ages 8 to 12 beginning ice-skating classes at the ice Chalet.
