    In a poll of 200 randomly selected U.S. adults, 104 said they favored a new proposition. Based on this poll, compute a 99% confidence interval for the proportion of all U.S. adults in favor of the proposition (at the time of the poll). Then complete the table below.

    Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places.

    (If necessary, consult a list of formulas.

    What is the lower limit of the 99% confidence interval?
    What is the upper limit of the 99% confidence interval?
