WebConfidence Intervals. Since the sample proportion p ^ 1 computed using the sample drawn from Population 1 is a good estimator of population proportion p 1 of Population 1 and the sample proportion p ^ 2 computed using the sample drawn from Population 2 is a good estimator of population proportion p 2 of Population 2, a reasonable point estimate of the … Webconfidence intervals that would actually contain the true population proportion. Notation: 1 The confidence level is denoted by −α Note: zThe critical value (denoted α2) is the positive z score that separates an area of α 2 in the right tail of the standard normal distribution. It is determined by the confidence level. Ex: Find z 0.02
