Question

A horizontal bar graph is titled Trainee Results of Groups upper A, upper B, and upper C. A legend below the graph shows that the solid bars indicate the number who failed, and the striped bars indicate the number who passed.

An aviation academy is reforming a study on the efficacy of new training materials developed to prepare trainees for comprehensive testing. The academy randomly separates the trainees into three groups. Group A is only permitted to use the current training materials. Group B is only permitted to use the new training materials. Group C is advised to use both the current and the new training materials. What is the passing rate to the nearest whole percent of Group B?

The passing rate to the nearest whole percent of Group B is
percent.

Answer 1

To determine the passing rate of Group B, we need to know the number of trainees who passed and the total number of trainees in Group B. Let’s assume based on the graph you referenced:

• The number of trainees who passed in Group B is represented by the striped bar.
• The total number of trainees in Group B can be calculated by adding the number of trainees who passed (striped bar) and the number of trainees who failed (solid bar).

The passing rate can be calculated using the formula:

\[ \text{Passing Rate} = \left( \frac{\text{Number of Passes}}{\text{Total Number of Trainees}} \right) \times 100 \]

Once you provide the specific numbers from the bar graph for Group B, I can help you calculate the passing rate to the nearest whole percent.
