Answer:
6.22
Step-by-step explanation:
First find the mean:
μ = (105+104+110+112+114+108+108+109) / 8
μ = 108.75
The standard deviation is then:
σ² = [(105-108.75)²+(104-108.75)²+(110-108.75)²+(112-108.75)²+(114-108.75)²+(108-108.75)²+(108-108.75)²+(109-108.75)²] / 8
σ² = 77.5 / 8
σ = 3.11
Margin of error is ±2σ, so ME = ±6.22.
