In: Statistics and Probability
Out of 500 people sampled, 115 preferred Candidate A. Based on this, estimate what proportion of the entire voting population (p) prefers Candidate A. Use a 90% confidence level, and give your answers as decimals, to three places. < p
Assume that a sample is used to estimate a population proportion p. Find the 90% confidence interval for a sample of size 366 with 102 successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places.
