Which of the following is true about the sampling distribution of means? A. Shape of the sampling distribution of means is always the same shape as the population distribution, no matter what the sample size is. B. Sampling distributions of means are always nearly normal. C. Sampling distributions of means get closer to normality as the sample size increases. D. Sampling distribution of the mean is always right skewed since means cannot be smaller than 0.
Which of the following is true about the sampling distribution of the sample means with over 30 samples? Multiple choice a. The standard deviation of the sampling distribution is equal to the population standard deviation divided by the square root of the sample size. b. The mean of the sampling distribution is equal to the population mean. c. The shape of the sampling distribution is always approximately normal. d. All of the choices are true.
