Answer: To find the percentage of bad units, we need to divide the number of bad units by the total number of units and then multiply by 100 to get the percentage.
Percentage of bad units = (number of bad units / total number of units) x 100
In this case, the total number of units is 256 and the number of bad units is 29.
- Percentage of bad units = (29 / 256) x 100
- Percentage of bad units = 0.11328125 x 100
- Percentage of bad units = 11.328125
Therefore, the percentage of bad units is approximately 11.33%.
