Extracted text: The central limit theorem says that the sampling distribution of the sample mean is approximately normal O a. if the sample size is large, regardless of the parent population O b. only if both the sample size is large and the parent population is normal O c. only if both the sample size is large and the values of the mean and the variance of the parent population are unknown O d. only if the mean and variance of the parent population are known O e. only it both the parent population is normal and themean of the parent population is known
