Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 128 with 50 successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places. blank < p < blank (fill in blank) Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
