Question

Find the mean of the following data set. Round to the nearest hundredth.(-7.0, 3.7, -9.1, 7.8, 2.0)

Answer 1

Answer: Mean = - 0.52

Explanation:

(-7.0, 3.7, -9.1, 7.8, 2.0)

Mean = (sum of terms)/number of terms

number of terms = 5

Sum of terms = - 7 + 3.7 - 9.1 + 7.8 + 2 = - 2.6

Mean = - 2.6/5

Mean = - 0.52
