IQR = 6
First locate the median at the centre of the data arranged in ascending order. Then locate the lower and upper quartiles
and
located at the centre of the data to the left and right of the median.
Note that if any of the above are not whole values then they are the average of the values either side of the centre.
rearrange data in ascending order
15 16 ↓17 17 18 21 22 ↓23 25
↑
= 18
=
= 16.5
=
= 22.5
IQR = -
= 22.5 - 16.5 = 6
Answer: $277.91
<u>Step-by-step explanation:</u>
The average of the 2 highest salaried quarters is:
Divide that by 26 (weeks) to find out her average weekly salary:
Multiply that by 55% (0.55) to calculate her weekly unemployment benefit:
Round to the nearest penny --> $277.91
Given:
x is a number between 8 and 12 exclusive.
To find:
The value of x.
Solution:
