Answer: - 1.3
Step-by-step explanation: I believe that it's -1.3 if you're referring to the arithmetic mean.
(1) Take the sum of -9, -5, -4, -4, -2, 0, 1, 2, 3, 5 and simplify it to -13
(2) Count the number of terms in the data set.
{-9, -5, -4, -4, -2, 0, 1, 2, 3, 5}
{1, 2, 3, 4, 5, 6, 7, 8, 9, 10} - The number of terms in the data set is <u>10.</u>
(3) Divide the sum by the number of terms and simplify.
-13 / 10 = -1.3 (simplified)
