Question:
Assume that the following sample statistics were obtained from a simple random sample. Which of the following statements are true?
a. The sample mean targets the population mean μ in the sense that the mean of all sample means is μ.
b. The sample proportion targets the population proportion p in the sense that the mean of all sample proportions is p.
c. The sample variance s2 targets the population variance σ2 in the sense that the mean of all sample variances is σ2.
d. The sample median targets the population median in the sense that the mean of all sample medians is equal to the population median.
e. The sample range targets the population range in the sense that the mean of all sample ranges is equal to the range of the population.
