Which Method?
A proponent of a new proposition on a ballot wants to know whether the proposition is likely to pass.
Suppose a poll is taken, and 580 out of 1000 randomly selected people support the proposition.
Should the proponent use a hypothesis test or a confidence interval to answer this question? Explain.
If it is a hypothesis test, state the hypotheses and find the test statistic, p-value, and conclusion.
If a confidence interval is appropriate, find the approximate 95% confidence interval.
In both cases, assume that the necessary conditions have been met.
