Finding the Confidence Interval for a Population Proportion In a sample, we have n=170 and ?=0.30. Use the normal distribution to find a 95% confidence interval for the population proportion p. Please round your answers to three decimal places. The 95% confidence interval is from 0.271 to 0.329. The 95% confidence interval is from 0.291 to 0.309. The 95% confidence interval is from 0.251 to 0.349. The 95% confidence interval is from 0.231 to 0.369.
