Answer 1

It's impossible to conclude which statement about hourly wages based on the box-and-whisker plots is valid without the actual plots for Fitness Plus and Fitness Center Fitness.

Step-by-step explanation:

To determine which statement must be valid about the hourly wages at Fitness Plus and Fitness Center Fitness based on the box-and-whisker plots, we would typically analyze metrics such as median, range, upper quartile, and lower quartile that are represented in such plots. However, given the information in the text, none of the provided statements can be confidently validated without the actual box-and-whisker plots for Fitness Plus and Fitness Center Fitness. In a typical scenario, you'd compare the medians for statement 1, the range for statement 2, the values of the upper quartile for statement 3, and the values of the lower quartile for statement 4. As we do not have the plots, we cannot make a valid statement about the provided options concerning the hourly wages at the two fitness centers.
