Question

Each of the Five cats and a pet strobe was weighed here are their weights in pounds 15, 9, 9, 11, 9. Find the median And mean weights of these cats if necessary round your answer to the nearest 10th

Answer 1

Hello there. To solve this question, we'll have to remember how to calculate the median and the mean of set of numbers.

Given the weight of the five cats:

15, 9, 9, 11, 9

We start by ordering the numbers:

9, 9, 9, 11, 15

Since this set has an odd number of entries, its median will be the center value:

9.

The mean of a set can be calculated by adding all the values and dividing it by the amount of numbers:

`(9+9+9+11+15)/(5)`

Adding the numbers

`(53)/(5)`

Calculating the fraction, we get:

`10.6`

This is the mean of the cats weights.
