Express The Confidence Interval In Interval Form - You can use it with any arbitrary confidence level. By the end of this chapter, the student should be able to: Interpret the student's t probability distribution as the sample size changes. If you want to know what exactly the confidence interval is and how to calculate it, or are looking for the 95% confidence. Calculate and interpret confidence intervals for estimating a population mean and a population proportion. The pollster will take the results of the sample and construct a 90 % confidence interval for the true proportion of all voters who support the candidate. In this module, we learned how to calculate the confidence interval for a single population mean where the population standard deviation is known. A political pollster plans to ask a random sample of 500 voters whether or not they support the incumbent candidate. Web this confidence interval calculator is a tool that will help you find the confidence interval for a sample, provided you give the mean, standard deviation and sample size.
