Question

Find the mean and median of the seven odd prime numbers

Answer 1

The seven odd prime numbers are- 3, 5, 7, 11, 13, 17, 19

First arrange in ascending order. Since it is already done, let us proceed with the mean.

There are 7 numbers. So add the 7 numbers and divide them by 7.

$\frac{3 + 5 + 7 + 11 + 13 + 17 + 19}{7}$

$= \frac{75}{7}$

$= 10 \frac{5}{7} is \: the \: mean$

Now find the median. Attached as image depicts that 11 is the median.
