Researchers conducted an observational study to investigate active commuting habits among employees at a large business park during a regional "Green Week" campaign. The researchers recorded whether employees under 30 and employees aged 30 and over chose active travel (cycling or walking) or motorized travel (driving or taking the bus) to arrive at work.
Table showing the commuting choices of employees under 30 and employees aged 30 and over
| Commuting Choice | Employees under 30 | Employees aged 30 and over |
|---|---|---|
| Chose active travel | 9 | 27 |
| Chose motorized travel | 21 | 13 |
Using the data in the table above, draw a fully labelled pie chart showing the percentage of employees under 30 compared to employees aged 30 and over who chose active travel.
