The expected value of the statistic represents the average value of the statistic over many repeated samples. This average value is the mean of the sampling distribution, which is D. A point estimate is a single value that is used to estimate a population parameter, but it is not necessarily the expected value of the statistic. A Z-statistic is a standardized version of a statistic that is used in hypothesis testing, but it is not necessarily the expected value of the statistic. The standard error of the mean is a measure of the variability of the sample mean, but it is not necessarily the same as the expected value of the statistic.
