A. The population median is equal to double the mean of the sample medians.
OB. The population median is equal to the mean of the sample medians.
OC. The population median is equal to half of the mean of the sample medians.
OD. The population median is not equal to the mean of the sample medians (it is also not half or double the mean of the sample medians).

c. Do the sample medians target the value of the population median? In general, do sample medians make unbiased estimators of population medians? Why or why not?
OA The sample medians target the population median, so sample medians are biased estimators, because the mean of the sample medians equals the population median.
OB. The sample medians target the population median, so sample medians are unbiased estimators, because the mean of the sample medians equals the population median.
OC. The sample medians do not target the population median, so sample medians are biased estimators, because the mean of the sample medians does not equal the population median.
OD. The sample medians do not target the population median, so sample medians are unbiased estimators, because the mean of the sample medians does not equal the population median.
