Answer 1

Mean = 6

● In the given question, there are 9 sample observations.

● “Mean” is the arithmetic simple average of given observations.

● Average means Sum of all observations divided by Total number of observations

The sum of given numbers = 4+6+8+3+7+8+3+9+6 = 54

● Total number of observations = 9

Therefore, the Mean = 54/9

=6
