Question

Let x be the median of the data
13, 8, 15, 14, 17, 9, 14, 16, 13, 17, 14,
15, 16, 15, 14.
If 8 is replaced by 18, then the median
of the data is y. What is the sum of the
values of x and y?
(1) 30
(2) 27
(4)29​

Answer 1

Answer: Hi mate!

Sum of x and y is 29

Step-by-step explanation:

Median of original data = 14

Therefore, x = 14

Median after replacing 8 with 18 = 15

Therefore, y = 15

Sum of x and y = 14 + 15

                         = 29
