Confidence Intervals for p
Confidence intervals for p are statistical estimates used to quantify the uncertainty around the proportion of a population that possesses a certain characteristic or attribute. In hypothesis testing, p represents the population proportion, and constructing a confidence interval for p involves determining a range within which the true population proportion is likely to lie with a specified level of confidence. This interval provides valuable information about the precision of the estimate and helps in making informed decisions based on sample data. Confidence intervals for p play a crucial role in various fields, including epidemiology, market research, and political polling, where accurate estimation of population proportions is essential.
