Select all statements that are TRUE. As the size of a sample increases, the mean of the distribution of sample means increases. If the size of a sample is at least 30, then you can use z-scores to determine the probability that a sample mean falls in a given interval of the sampling distribution. As the size of a sample increases, the standard deviation of the distribution of sample means increases. A sampling distribution is normal only when the population is normal
