Answer 1

Answer: B. 2

Step-by-step explanation: When you solve for mean, you have to add all the numbers together, then whatever your answer is, then divide it with the number of values.

3 + 1 + 2 + 3 + 1 + 2 + 3 + 1 + 2 + 1 + 3 + 2 = 24

24 divided by 12 = 2

The students spent an average of 2 hours studying.

Answer 2

Answer: B 2

Explanation:

We can find the mean of the data set by adding all the numbers together and dividing by the number of numbers.

`\displaystyle (3+ 1+2+ 3+ 1+ 2+ 3+ 1+ 2+ 1+ 3+ 2)/(12) =(24)/(12) =2`
