### statistics

A survey is being conducted of voters’ opinions on several different issues.
(i) What is the overall margin of error of the survey, at 95% confidence, if it is based on a
simple random sample of 1111 voters.
(B) A political party had claimed that it has the support of 23% of the electorate. Of the
voters in the sample above, 234 stated that they support the party. Is this sufficient
evidence to reject the party’s claim, at the 5% level of significance?

does anyone know how to work this out. i can do the first part easy its 1/√1111 i dont know how to do the second part b

### Re: statistics

Why is that the correct value for part (a)?

What does margin of error mean? What does the poll say the actual percentage is? What is the 5% level of significance?
(∫|p|2)(∫|q|2) ≥ (∫|pq|)2
Thanks, skeptical scientist, for knowing symbols and giving them to me.
