Megan ran an analysis with a population standard deviation? = 0.90. When reviewing sample sizes of 4 and 8, the standard error for the sample mean was = 0.45 and = 0.32 respectively. Doing a comparison, what does the expected value and the standard error of the sample mean reflect? A) By comparison, the results confirm the sample is normally distributed with increased variability. B) The standard error for the sample mean is lower confirming the initial population standard deviation is incorrect. C) By comparing, the results confirm that averaging reduces variability. D) The standard error for the sample mean is lower, increasing variability in the sample set.
