How many trout were less than 20 inches long? Hint: 20 inches is the upper quartile of the box-and- whisker plot. So, 75% of the trout were less than 20 inches long. To find the answer: multiply the percentage (75%) x 20 (the number of inches) We use 75% because that is the Q3 in the data. 25% would be our Q1 and 50% is the median (or Q2).

Question
**Box-and-Whisker Plot Analysis of Trout Lengths** The box-and-whisker plot below represents the length, in inches, of 20 trout caught at Raystown Lake in one weekend. **Length of Trout (inches)** [Diagram Explanation] - The box-and-whisker plot consists of a number line ranging from 10 to 30 inches. - The box indicates the interquartile range, with the left edge at approximately 12 inches (the lower quartile, Q1) and the right edge at 20 inches (the upper quartile, Q3). - The line inside the box marks the median (Q2) at around 15 inches. - Whiskers extend from the box to the minimum at 10 inches and maximum at 28 inches. **Question:** How many trout were less than 20 inches long? **Hint:** 20 inches is the upper quartile of the box-and-whisker plot. So, 75% of the trout were less than 20 inches long. **Solution:** To find the answer: multiply the percentage (75%) by 20 (the total number of trout). We use 75% because that is the Q3 in the data. 25% would be our Q1, and 50% is the median (Q2).
