Consider the following data which describe the amount of time in minutes students spend studying for a quiz: 10, 11, 11, 12, 12, 14, 15, 18, 19, 20, 22, 24, 39, 40, 41, 44, 46, 50, 52, 52, 53, 55, 70. What numbers make up the leaf of the first stem if you were splitting the stems?

A) 0,1,1,2,2,4,5,8,9

B) 0,1,2,4,5,8,9

C) 0,1,1,2,2,4

D) 0, 1, 2, 4

Answer: A) 0,1,1,2,2,4,5,8,9

Step-by-step explanation:

We know that in a stem leaf plot,

The stem represents the tens value of the term and leaves represent the ones values of the data.

Given data of the amount of time in minutes students spend studying for a quiz:

10, 11, 11, 12, 12, 14, 15, 18, 19, 20, 22, 24, 39, 40, 41, 44, 46, 50, 52, 52, 53, 55, 70.

Here, the least tens value is 1. (10, 11, 11, 12, 12, 14, 15, 18, 19)

So the first stem would have value.

Then the leaf of the first stem if you were splitting the stems contains all the ones-values corresponding to tens value as 1 (10, 11, 11, 12, 12, 14, 15, 18, 19).

= 0, 1, 1,2, 2, 4, 5, 8, 9

Hence, the correct answer is A) 0,1,1,2,2,4,5,8,9
