A ✩ The box-and-whisker plot below represents the length, in inches, of 20 trout caught at Raystown Lake in one weekend. 4466619/varlants/5145485/take/5/ 10 Length of Trout (inches) H 15 20 H 25 30 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).

Use a stem-and-leaf plot to display the data, which represent the thickness (in centimeters) of ice measured at 20 different locations on a frozen lake.

Key: 3|3 = 3.3 Ice Thickness 6| 8 What best describes the data? A. Most thicknesses are greater than 7 centimeters. B. Most thicknesses are 6 centimeters. C. Most thicknesses are between 5 and 8 centimeters. D. Most thicknesses are less than 5 centimeters.
