1 answer:
Answer: Lower = 1 Median = 2 Upper = 4
Upper ≠ 1 so statement is false
<u>Step-by-step explanation:</u>
The Lower quartile (Q1) is the left side of the box.<em> I estimate it to be 1.</em>
The Median (Q2) is the line dividing the box.<em> I estimate it to be 2.</em>
The Upper quartile (Q3) is the right side of the box.<em> I estimate it to be 4.</em>

The upper quartile is the 75th percentile. It is not 1 so the statement is false.
