Assume that a sample is used to estimate a population proportion p. Find the 90% confidence interval fo sample of size 168 with 32.1% successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places. < p < Answer should be obtained without any preliminary rounding. However, the critical value may be rounde to 3 decimal places.
