Suppose we take repeated random samples of size 20 from a population with a mean of 60 and a standard deviation of 8. Which of the following statements is true about the sampling distribution of the sample mean (x)? Check all that apply.
-The distribution is normal regardless of the shape of the population distribution, because the sample size is large enough.
-The distribution will be normal as long as the population distribution is normal.
-The distribution's mean is the same as the population mean 60.
-The sampling distribution's standard deviation is larger than the population standard deviation of 8.
