When performing inference on population means we require that the data are normal and/or that the sample size is large (to use the Central Limit Theorem) so that the sample means have a sampling distribution that is at least approximately normal. The exact same statement (in bold) holds for performing inference on population variance(s) using the χ 2 or F-test.

(a) True

(b) False

The Central Limit Theorem says that when sample size n is taken from any population with mean μ and standard deviation σ when n is large, which of the following statements are true? The distribution of the sample mean is approximately Normal. The standard deviation is equal to that of the population. The distribution of the population is exactly Normal. The distribution is biased.

The central limit theorem states that: Populations with more than 30 observations are approximately normally distributed. As the sample size increase, a sampling distribution will look more and more like the population. As long as the sample size collected is at least 30, the variable of interest will always be approximately normally distributed. A skewed-left population can never be a sampling distribution that is approximately normally distributed. For sufficiently large random samples, the sampling distribution of the sample mean is...

Hello, please review the statement below and determine if the statement is right or not (and why). Explain the central limit theorem The central limit theorem states that when there’s a large enough sample size (generally 30 or more) with a finite level of variance, then the mean from all of the samples, from the same population, will be approximately equal to the mean of the population. There are three different components of the theorem. The first is successive sampling...
