Which list shows all the stems needed to accurately create a stem-and-leaf plot?

A 3
B 3, 4, 5, 6, 7, 8, 9
C 0, 1, 2, 4, 5, 6, 7, 8, 9
D 33, 34, 35, 36, 37, 38, 39

Answer 1

D. 33, 34, 35, 36, 37, 38, 39

Explanation:

Remember, in a stem-and-leaf plot, stem refers to the whole part of a decimal number, and leaf refers to the decimal part.

So, in this case, all the stems to build correctly a stem-and-leaf plot are: 33, 34, 35, 36, 37, 38, 39.

Beacuse all this number enclosed all whole number parts from the data set, which goes from 33.6 to 39.7.

Therefore, the right answer is D.
