Question

Three randomly selected households are surveyed. The numbers of people in the households are 2,6, and 13. Assume that samples of size n=2 are randomly selected with replacement from the population of 2, 6, and 13. Listed below are the nine different samples. Complete parts (a) through (c) 2,2 2,6 2,13 6,2 6,6 6,13 13,2 13,6 1313 Sample Median Probability Type integers or fractions. Use ascending order of the sample medians.) b. Compare the population median to the mean of the sample medians. Choose the correct answer below. O A. The population median is equal to the mean of the sample medians O B. The population median is equal to double the mean of the sample medians O C. The population median is equal to half of the mean of the sample medians 0 D. 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 good estimators of population medians? Why or why not? 0 A The sample medians do not target the population median, so sample medians do not make good estimators of population medians. B. C 0 D. The sample medians do not target the population median, so sample medians make good estimators of population medians The sample medians target the population median, so sample medians make o esti ators of population medians. The sample medians target the population median, so sample medians do not make good estimators of population medians Click to select your answer(s).
