Question

IF A is the median of {1,2,3...,10}, and B is the median of 1,2,3,4,...11, what is the average (arithmetic mean) of A and B? Express your answer as a decimal? "{}" is no different from B

Answer 1

1 2 3 4 5 ---- 5.5 ---- 6 7 8 9 10

1 2 3 4 5 ----- 6 ----- 7 8 9 10 11

so A = 5.5
B = 6

11.5/2 = 5.75
