Answer 2

Answer:

Mean is 10

Median is 10

There is no mode

Step-by-step explanation:

Mean = Sum of observations / No. of observation

Mean = 3+13+12+10+17+7+8 / 7

Mean = 70 / 7

Mean = 10

Median is 10 because median is always the middle most value.

There is no mode because mode is repeating

value and in the given question there is no repeating value.
