2.Which of the following statements are true regarding the general properties of sampling distributions?
The sampling distribution of a statistic often tends to be centered at the value of the population parameter estimated by the statistic.
The spread of the sampling distributions of many statistics tends to grow smaller as the sample size n increases.
As the sample size increases, sampling distributions of many statistics become more and more bell-shaped (more and more like normal distributions)
All of the above
