There is a clear bias. It is important however to not look at how many women got promoted with respect to men but which proportion of each subset got promoted. In the man files, 21/24 got promoted; this is a very high percentage, equal to 87.5%. Nonetheless, regarding women, 14/24 got promoted, 58,3%, barely over half of them. Hence, we conclude that there is a significant bias that favors male workers.
The amount spent based on the information in the pie chart include:
Transportation = $187.50
Lunch = $375
Entertainment = $225
Others = $112.50
<h3>How to illustrate the information?</h3>
From the information, the following can be deduced:
Amount spent = $900
Transportation = 75°
Lunch = 150°
Entertainment = 90°
Therefore, Others will be:
= 360° - (150° + 75° + 90°)
= 360° - 315°
= 45°
Transportation = 75° = 75/360 × $900 = $187.50
Lunch = 150° = 150/360 × $900 = $375
Entertainment = 90° = 90/360 × $900 = $225
Others = 45° = 45/360 × $900 = $112.50
