Answer: 38, 40, 42; 45, 44, 46; 50, 49, 51

Question 9: Identify the mistake in this stem and leaf diagram: Stem 1 | Leaves 2, 4, 6; Stem 2 | Leaves 1, 3, 5. The data is 12, 14, 16, 21, 23, 25.

Answer: Incorrect ordering of leaves; should be 2, 4, 6 for stem 1 and 1, 3, 5 for stem 2. Also, the data should be ordered correctly as 12, 14, 16, 21, 23, 25.
