Which is true for the sampling distribution of the sample mean (note multiple answers may be correct)?

A. The standard deviation for the sample mean is always less than the standard deviation for the underlying population that created the mean.

B. The sample mean will only follow a normal distribution if the sample from which the mean was constructed is also a normal distribution.

C. The sample mean will follow a normal distribution only if the sample constructing the mean is greater than 30.

D. All of the above are correct. E. None of the above are correct.

The purpose of this is to demonstrate the sampling distribution of the sample mean when the data is generated from an exponential distribution (at rate 2.0) as sample size increases. Describe and compare the sampling distributions of the sample mean for sample sizes n=5, n=20, n=40. Do this by simulating samples at least 5000 times. R-code for generating a sample of size n=10 from exponential distribution at rate 2.0 is >rexp(n=10, rate=2.0)

Purpose: To explore the sampling distribution for sample proportions. Materials: One package of candies with multiple colors (M&M’s – any variety, Skittles – any variety, Reese’s Pieces, etc.). You may select any size package but be mindful of the “sample size” which will vary depending on the type of candy you choose. You may want to purchase at least a king size package to ensure you end up with a sample size that is “large enough.” Select a color whose...

True of False the sampling distribution of a parameter is the distribution of the parameter value if repeated random samples are obtained The central lmit theorem is important in statistics because for a large random sample, it says the sampling distribution of the sample mean is approximately normal
