lower boundary is - 5.
what is 1.5iqr above q3?
19.5
16
18.75
23

Explanation:

Step1: Identify Q3 and IQR values

From the five - number summary, \(Q3 = 12.5\) and \(IQR=7\)

Step2: Calculate \(1.5IQR\) above \(Q3\)

Use the formula \(Q3 + 1.5\times IQR\). Substitute \(Q3 = 12.5\) and \(IQR = 7\) into the formula:

$$12.5+1.5\times7=12.5 + 10.5$$

$$12.5+10.5=23$$

Answer:

23
