□, □, □, □, □
iqr = □
question help: message instructor
submit question

Explanation:

Step1: Identify min from boxplot

The leftmost whisker ends at 11, so min = 11.

Step2: Identify Q1 from boxplot

The left edge of the box is at 12, so Q1 = 12.

Step3: Identify median from boxplot

The line inside the box is at 15, so median = 15.

Step4: Identify Q3 from boxplot

The right edge of the box is at 18, so Q3 = 18.

Step5: Identify max from boxplot

The rightmost whisker ends at 19, so max = 19.

Step6: Calculate IQR

IQR = Q3 - Q1 = $18 - 12$

Answer:

5 number summary: 11, 12, 15, 18, 19
IQR = 6
