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...

(Check all that apply) A distribution of sample means may not be normally distributed. D A sampling distribution always has a bigger standard deviation than that of it's corresponding population sample means are approximately normally distributed when n 30. The standard deviation of a sampling distribution of means is the standard deviation of the or ginal population divided by n (the sample size).
