Assume that a sample is used to estimate a population proportion
p. Find the 99% confidence interval for a sample of size 356 with
320 successes. Enter your answer as an open-interval (i.e.,
parentheses) using decimals (not percents) accurate to three
decimal places.
99% C.I. =
Answer should be obtained without any preliminary rounding.
However, the critical value may be rounded to 3 decimal places.
