The margin of error is obtained as the ratio of the standard deviation and the square root of the samplesize. It is a measure of the amount of difference that is expected to exist between the actualpopulation value and the value obtained from the sample.
<em>Margin of Error = ±0.01</em>
<u>Margin of Error can be calculated using the relation</u> :
Margin of Error = σ/√n
Margin of Error = 0.228 ÷ √500 = 0.010
Therefore. the margin of error can be interpreted to mean that the value of themean obtained from the sample is expected to differ from the mean of the population weight by ±0.01
