The $5P.M$., Monday night, ages $8$to $12$, beginning ice-skating class was picked. In that class were $64$girls and $16$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.

State the estimated distribution of $P′$. Construct a $92\%$Confidence Interval for the true proportion of girls in the ages $8$ to $12$ beginning ice-skating classes at the Ice Chalet.
