A university researcher investigated the impact of 'gamified' recycling bins on waste disposal behavior in a student union building. They compared two waste disposal setups: one 'Interactive Bin' that played a pleasant chime and lit up when waste was deposited, and one 'Standard Bin' of the same size with no sensory feedback.
The researcher recorded each time a student or staff member used either bin during a busy lunch hour. The observational data is presented in the table below.
| Students | Staff | |
|---|---|---|
| Interactive Bin | 29 | 15 |
| Standard Bin | 14 | 8 |
Draw a fully labelled bar chart showing the overall use of the two different types of recycling bin.
