Q6: Using minitab: The normal distribution is sometimes used to approximate the distribution of Poisson when n is large and p is small. A common rule of approximation is that which requires both conditions: a) n is greater than or equal to 100. b) np is smaller or equal to 10. Compare the values given by the two distributions for n=150 and p=0.05

Decide whether the normal sampling distribution can be used. If it can be used test the claim about the population proportion p at the given level of significance α using the given sample statistics. Claim: p < 0.12; α-0.10; Sample statistics: p-0.08, n-25 Can the normal sampling distribution be used? O A. No, because np is less than 5. O B. Yes, because pq is greater than α = 0.10 C. No, because nq is less than 5. O D....

If I has a normal distribution, then 7 always has a normal distribution. True False Under what condition does the sample mean ī not have a normal distribution? Population is not normal but the sample size n > 30. Population is not normal and sample size n <30. Population is normal. The Central Limit Theorem for a sample mean (@) is very important in Statistics because it states that for large sample sizes, the population distribution is approximately normal. for...
