Why is the Central Limit Theorem useful? [Q8P5.3] a. Because when the conditions for the CLT are met, it allows us to use a Normal distribution to approximate the distribution of the whole population, even if we don't know whether the population follows a Normal distribution. Because when the conditions of the CLT are met, it allows us to calculate the area in the tails of the population distribution and therefore the probability of obtaining an observation as or more...

QUESTION 3 According to the central limit theorem, which of the following distributions tend towards a normal distribution? (choose all that apply) a. Binomial distribution as number of events (number of total coin flips) increase U b.Sum of m independent samples from a normal distribution as m increases UC. Mean of n independent samples from a chi-squared distribution as n increases d. Sampling distribution of the mean from ANY population distribution as the sample size increases

17. According to the Central Limit Theorem, a distribution of sample means based on a sample of n= 7 will approximate normality even if the data in the parent population are not normal. 18. When performing hypothesis tests or computing confidence intervals based on large samples, it is necessary to assume that the data in the parent population(s) are distributed normally. 19. To estimate u within two units with 95% confidence and o= 10 requires n be at least 100.
