Answer 2

Answer:

The average number of biscuits they ate is 4.

Step-by-step explanation:

• Average is defined as the mean of the observations.
• Mean is the total sum of the observation divided by the total number of observations.
• Mean  is given by

        $Mean=\frac{sum\ of \ observation}{Number\ of \ observations}$

Step 1 of 1:

• Form a table containing a number of students and the number of biscuits eaten

• The table is attached as a file.

• Total number of students=10
• Total number of biscuits= $8+12+12+8=40$
• $Mean=\frac{sum\ of \ observation}{Number\ of \ observations}$

         $Mean=\frac{40}{10}\\Mean=4$
