The following are the weekly amounts of welfare payments made by the federal government to a sample of six families: $143, $138, $132, $136, $145 and $136. What is the range?
$24
$9
$13
$0
Range= highest value -lowest value
Range = $145 - $132 = $13
Thank you
To find the range, you need to subtract the smallest value from the largest value in the data set.
In this case, the smallest amount is $132 and the largest amount is $145.
Range = Largest value - Smallest value
Range = $145 - $132
Range = $13
Therefore, the range of the welfare payments is $13.
To find the range, which is the difference between the highest and lowest values in a set of numbers, you need to follow these steps:
1. Arrange the given numbers in ascending order: $132, $136, $136, $138, $143, $145.
2. Identify the lowest value, which is $132.
3. Identify the highest value, which is $145.
4. Calculate the range by subtracting the lowest value from the highest value: $145 - $132 = $13.
Therefore, the range of the weekly welfare payments is $13. So the correct answer is: $13.
