Question

In a recent survey of 230 voters, 62% of them in the upcoming election. which of the following is closest to the margin of error for this statistic

Answer 1

The sample size 230 here.

Among them 62% is them in the upcoming election.

Hence they are

`(62)/(100)*230=142`

in number.

now we have to find the population standard deviation with the sample size 230.

It is given by

`(142)/(230)=0.62`

Hence the margin of error is given

`0.62*10=6.2`

Hence the closest margin value is 6.4%
