Question 4

An engineer measures the volume of gas produced (in $cm3\text{cm}^3$ ) during a chemical reaction at four different temperature conditions, W, X, Y, and Z. She performs 3 trials for each temperature condition.

Table of measurements:

Temperature W: 42.15 cm³, 42.19 cm³, 42.17 cm³
Temperature X: 35.84 cm³, 35.95 cm³, 35.81 cm³
Temperature Y: 28.62 cm³, 28.78 cm³, 28.65 cm³
Temperature Z: 19.33 cm³, 19.38 cm³, 19.34 cm³

Which temperature condition, W, X, Y, or Z, has the largest range of values? Show your working.
