Doctors measure the concentration of cholesterol in the blood of four patients to evaluate their health.

The table below shows four different blood cholesterol categories:

Blood cholesterol concentration in mmol/dm3\text{mmol/dm}^3mmol/dm3Cholesterol category
<4.5< 4.5<4.5Low
4.5–5.24.5\text{--}5.24.5–5.2Normal
5.3–6.35.3\text{--}6.35.3–6.3Medium
6.4 and above6.4\text{ and above}6.4 and aboveHigh

The graph below shows the blood cholesterol concentration of four patients: W, X, Y, and Z.

A bar chart showing the blood cholesterol concentration of four patients. The vertical y-axis is labeled "Blood cholesterol concentration in mmol/dm³" and ranges from 0 to 8. The major grid lines are at intervals of 1, and the minor grid lines are at intervals of 0.2. The horizontal x-axis is labeled "Patient" and has four categories: W, X, Y, and Z. The bars have heights as follows: bar W is at 4.0, bar X is at 4.8, bar Y is at 6.0, and bar Z is at 7.2.

The blood cholesterol concentration of patient Z is greater than the blood cholesterol concentration of patient W.

Calculate how many times greater.
