A soft-drink bottling company fills and ships soda in plastic bottles with a target volume of 354 milliliters. The filling machinery does not deliver a perfectly consistent volume of liquid to each bottle, and the three quartiles for the fill volume are $Q _ { 1 } = 354 , Q _ { 2 } = 358$ and $Q _ { 3 } = 362$. Find the IQR.
A) 8
B) 12
C) 4
D) 9.6

Quizplus · Accepted Answer

The interquartile range (IQR) is calculated as $Q_3 - Q_1$. Here, $Q_3 = 362$ and $Q_1 = 354$, so the IQR is $362 - 354 = 8$.

A Soft-Drink Bottling Company Fills and Ships Soda in Plastic Q1=354,Q2=358Q _ { 1 } = 354 , Q _ { 2 } = 358Q1​=354,Q2​=358
