Question1) If np ? 5 and nq, estimate P(fewer than 5) with n= 13 and p = 0.5 by using the normal distribution as an approximation to the binomial distribution; if np????<5 or nq<5, then state the normal approximation is not suitableP( fewer than 5)=2) If np ? 5 and nq, estimate P(fewer than 8) with n= 14 and p = 0.6 by using the normal distribution as an approximation to the binomial distribution; if np????<5 or nq<5, then state the normal approximation is not suitable.P(fewer than 8)=3) If np ? 5 and nq, estimate P(more than 4) with n= 11 and p = 0.3 by using the normal distribution as an approximation to the binomial distribution; if np????<5 or nq<5, then state the normal approximation is not suitableP(more than 4)=4) If np ? 5 and nq, estimate P(at least 7) with n= 13 and p = 0.6 by using the normal distribution as an approximation to the binomial distribution; if np????<5 or nq<5, then state the normal approximation is not suitableP(at least 7)=5) Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 108 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 30 voted.The probability that fewer than 30 of 108 eligible voters voted is nothing6) Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 137 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 exactly 32 .The probability that exactly 32 of 137 eligible voters voted is
