Answer:

Mean = 11.8

Median = 11

Step-by-step explanation:

Here we are asked to calculate the median and the mean for these set of numbers

Let’s start with the mean

The mean refers to the average, we simply add all the numbers together and divide by their count.

That would be;

Arithmetic mean = (10+ 5 + 18 + 9 + 17 + 12)/6 = 71/6 = 11.833 which is 11.8 to the nearest tenth

To get the median, what we do is to first rearrange the values we have from the lower to the highest.

That would be;

5,9,10,12,,17,18

Looking at the numbers after rearranging, the two middle numbers we have are 10 and 12.

So we add these together divide by 2.

That would be (10+12)/2 = 22/2 = 11
