Please help
D is it
I must admit that I had no idea what a "box and whisker" plot is, even though I taught math for 35 years,
so I looked it up and found this video of the very useful Khan Academy by Sal Khan

It's D. No one scored higher
What are the answers to the test??

To determine how Josh's score compares to those of his classmates, you need to analyze the box-and-whisker plot. The box-and-whisker plot provides information about the distribution of the scores and includes several key components.
First, locate the box in the plot. The box represents the interquartile range (IQR), which contains the middle 50% of the scores. The lower boundary of the box represents the 25th percentile, and the upper boundary represents the 75th percentile. This means that approximately 25% of the scores are below the lower boundary of the box, and approximately 75% are below the upper boundary.
Next, look for the line inside the box. This line represents the median, which indicates the score that separates the lower 50% from the upper 50% of the scores.
Based on the information provided, Ms. Alison's box-and-whisker plot can help determine how Josh's score compares to his classmates. Assuming that Josh's score is not an outlier, if his score falls within the box (between the 25th and 75th percentiles), then approximately 25% of the scores are higher than his, and approximately 75% are lower. Therefore, the correct answer is: About 25% scored higher; about 75% scored lower.
