Correct Answer: Option E
Explanation:
To calculate the mean of the numbers, use the formula:
\[
\text{Mean} = \frac{\text{Sum of all numbers}}{\text{Total number of numbers}}
\]
Given numbers: \(1.2, 1.0, 0.9, 1.4, 0.8, 0.8, 1.2, 1.1\)
Step 1: Add the numbers together.
\[
1.2 + 1.0 + 0.9 + 1.4 + 0.8 + 0.8 + 1.2 + 1.1 = 8.4
\]
Step 2: Divide the sum by the total count of numbers.
\[
\text{Mean} = \frac{8.4}{8} = 1.05
\]
E. 1.05
