given the number 10,12,9,15,8 what number should be included so that the median is 11

Answer 1

The numbers need to be rearranged in order: 8, 9, 10, 12, 15.

To find the median, we need to find the middle number. Since there are 5 numbers in total, the middle number is the 3rd number.

So, the median is 10.

To make the median 11, we need to include a number that is greater than 10.

We can include the number 13 to make the median 11.

The new set of numbers would be: 8, 9, 10, 12, 13, 15 and the median would be 11.
