The correct answers are: [A]: "6 " ; and: [B]: " 16 ."

____________________

Step-by-step explanation:

The question asks to find the modes of the following sets of numbers:
Set a) "{3, 13, 6, 8, 10, 5, 6}."

Set b) "{12, 0, 15, 15, 13, 19, 16, 13, 16, 16}."

Note that the mode is the number that occurs most frequently within a data set.

To begin: let's find the mode of Set: a:
_____
First, let's list all the values within Set: a: in order of smallest to largest—to simplify matters:
→ " { 3, 5, 6, 6, 8, 10, 13 }."
In this data set, there is only one value that occurs more than once—
which is 6. As such, the mode of "Data Set: a" is 6 .

Then: To continue: let's find the mode of Set: b:
_____

Second, Let's list all the values within Set: b: in order of smallest to largest—again; to simplify matters:
→ " { 0, 12, 13, 13, 15, 15, 16, 16, 16, 19 } ."
In this data set, we see the following:
Each of the three values: 0, 12, and 19 appear only once;
13 and 15 individually, appear twice; and:
16 appears "three times".
As such:
The value, 16 appears the most in this data set; and:
The mode of "Data Set: b"—is 16.
_____
The correct answers are: [A]: "6 " ; and: [B]: " 16 ."

Hope this is helpful to you!

Explanation:

a.

The mode is the number that appears the most

3 appears once

13 appears once

6 appears twice

8 appears once

10 appears once

5 appears once

Since 6 appears the most, it is the mode in this set of numbers

b.

Again, The mode is the number that appears the most

12 appears once

0 appears once

15 appears twice

13 appears twice

19 appears once

16 appears three times

Since 16 appears the most, it is the mode in this set of numbers
