I can help, but I can't see the box plots you mention. Could you either upload the image or tell me the five-number summaries (minimum, Q1, median, Q3, maximum) for the 7th and 8th graders?
Meanwhile, here’s how to check each choice on the box plot yourself:
- A (minimums): Compare the left ends of the whiskers. If the 7th-grade whisker starts farther left (smaller hours) than the 8th-grade whisker, A is true.
- B (medians): Compare the line inside each box. If the 7th-grade median line is left of the 8th-grade median line, B is true.
- C (ranges): Compute range = maximum − minimum (distance from left whisker end to right whisker end). If the 7th-grade range is smaller than the 8th-grade range, C is true.
- D (IQRs): Compute IQR = Q3 − Q1 (length of the box). If the 7th-grade box is longer than the 8th-grade box, D is true.
Send the image or the five-number summaries and I’ll pick the best-supported statement.
