4. Porter recorded the lengths of 8 earthworms, rounded to the nearest inch. A circle graph shows: • 37.5% are less than 5 inches • 50% are between 5 and 6 inches • 12.5% are greater than 6 inches A line plot shows the same data, with X marks at 3, 4, 5, 5, 6, 6, 6, and 7 inches. What information can be determined from both the circle graph and the line plot?
Show answer
Answer: C — The percent of earthworms greater than 6 inches long
