Step-by-Step Solution
Merge and sort: 11, 14, 15, 18, 19, 22, 23, 26, 27. The 5th value is 19. (19.5 wrongly averages the two group medians, 19 and 20; 20 is the median of group B alone.)
Answer: B) 19
Group A holds 11, 15, 19, 23 and 27; group B holds 14, 18, 22 and 26. What is the median of all nine values taken together?
