Answer:

The margin of error for the given values is 0.33725

Explanation:

The margin of error expresses the maximum expected difference between the true population parameter and a sample estimate of that parameter. To be meaningful, the margin of error should be qualified by a probability statement (often expressed in the form of a confidence level).

Margin error =
c((o)/(√(n)))

Now substituting the values we get

Margin error =
0.95((3.2)/(√(81)))

Margin error =
0.95((3.2)/(9))

Margin error =
0.95((3.2)/(9))

Margin error =
0.95 * (0.355)

Margin error = 0.33725
