Answer:
mean=6+8+8+9+9+10divided 6 =
1.
Step-by-step explanation:
The mean score is (8+6+9+9+8+8)/ 6
= 48/8
= 8.
Deviations from the mean are 0 , -2, 1, 1, 0, 0
Squares of these deviations are 0, 4, 1, 1, 0, 0
So the variance = (0 + 4 + 1 + 1 + 0 + 0)/ 6 = 1
Standard deviation = √1 = 1.
6 and 5 over 6
6 5/6
it would be a mixed fraction because 6 can't go into 41 evenly
