A simple random sample of size n=40 is obtained from a population with a mean of 20 and a standard deviation of 5. Is the sampling distribution normally distributed? Why? Yes, the sampling distribution is normally distributed because the sample size is greater than 30. Yes, the sampling distribution is normally distributed because the population is normally distributed. ) No, the sampling distribution is not normally distributed because the population is not normally distributed. O No, the sampling distribution is not normally distributed because the population mean is less than 30.
