Anewspaper article reported that 72% supported the 10–2 verdict.Suppose that the sample size for this survey wasn = 900.Compute a 99% confidence interval for theproportion of Californians who favor the 10–2 verdict.
Interpret the interval.
We are confident that 99% of the proportion of Californians whofavor the 10–2 verdict is within this interval.
We are 99% confident that the proportion of all people who favorthe 10–2 verdict is within thisinterval.
We are confident that the proportion of all people who favor the10–2 verdict is within this interval at least 99% of the time.
We are 99% confident that the proportion of Californians whofavor the 10–2 verdict is within this interval.
