Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 155 with 20 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 95% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

This problem demonstrates how to calculate the confidence interval for a population proportion. After, you will be asked to redo the calculations (with small variations). A survey was conducted to determine how many people were in favor of a proposed law to criminalize texting while driving. Response options included strongly disagree, disagree, neither agree or disagree, agree, and strongly agree. The survey asked a random sample of 800 18- to 25-year-olds, and 648 indicated agreeing or strongly agreeing with the...

Recall the formula for a proportion confidence interval is p^?zp^(1?p^)n?????????<p<p^+zp^(1?p^)n????????? Thus, the margin of error is E=zp^(1?p^)n????????? . NOTE: the margin of error can be recovered after constructing a confidence interval on the calculator using algebra (that is, subtracting p^ from the right endpoint.)
