Step-by-step explanation:
Given
Required
The IQR
The IQR is calculated using:
Where:
Median of the upper
Median of the lower
The dataset has 7 values, so the median is: (7 + 1)/2 =8/2 = 4th position.
Split to two, we have:
The lower half has 3 data; So, the median is the 2nd position.
Hence:
The upper half has 3 data; So, the median is the 2nd position.
Hence:
So, the IQR is:
Answer:
9
Step-by-step explanation:
Ratio of areas = (Ratio of sides)²
2025/25 = (feet/inch)²
sqrt(2025/25) = feet/inch
feet/inch = 9
