what is 1.5iqr below q1?
1.5
-5
12.5
3.5

Explanation:

Step1: Recall the formula

The formula for \(1.5IQR\) below \(Q1\) is \(Q1 - 1.5\times IQR\).

Step2: Substitute the values

Given \(Q1 = 5.5\) and \(IQR=7\).
Substitute into the formula: \(5.5-1.5\times7\).
First calculate \(1.5\times7 = 10.5\).
Then \(5.5 - 10.5=- 5\).

Answer:

-5
