Answer: its the first one
Step-by-step explanation: the key shows how the stem-and-leaf plot works. The numbers are 0, 4, 11, 13, 13, 20, 20, 26, 27, 27, 27, 30, 30, 30, 30, 31. There are 2 numbers that only have 1 digit, 3 numbers that have 1 at the tens place, 6 numbers that have 2 at the tens place, and 5 numbers that have 3 at the tens place. If you count the numbers, the first one will be correct.
