Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 111 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that fewer than 28 voted The probability that fewer than 28 of 111 eligible voters voted is El. (Round to four decimal places as needed.) If np 2 5 and nq 2 5, estimate P(fewer than 4) with n = 13 and p = 0.5 by using the normal distribution as an approximation to the binomial distribution; if np
