1. Use the normal approximation to find the indicated probability. The sample size is n, the population proportion of successes is p, and X is the number of successes in the sample. n = 77, p=.33 ; find: P (Xs 18 ) 2. Use the normal approximation to find the indicated probability. If n = 100 and p = 0.85, Find P(X at least 82)
