Answer:
x = 11
Explanation:
Median = The middle value of the set
There are 8 data values in the data set. You can split it up by 2 in order to get 4 and 4. There are two middle numbers that make up the median
3 4 7 9 x 12 14 18
We know that in order to find the median, we have to divide the two numbers by 2. If the median is 10, 10 by 2 equals 20. 9 plus 11 equals 20,
3 4 7 9 11 12 14 18
x = 11
