4.4 is correct hope this helps

Answer 2

first add all of the numbers together to get 55 then divide them by 5 to get 11 then subtract all of the numbers from the mean so,
11-10=115-11=418-11=711-8=311-4=7then add all of the numbers together to get 22 then divide that by 5 to get 4.4 so there you go your answer is 4.4
