Calculate margin of error confidence interval
WebJul 1, 2024 · The confidence interval is (7 – 2.5, 7 + 2.5) and calculating the values gives (4.5, 9.5). If the confidence level ( CL) is 95%, then we say that, "We estimate with 95% confidence that the true value of the population mean is between 4.5 and 9.5." Exercise 7.2.1. Suppose we have data from a sample. WebSo I am reviewing stats for grad school and my school provides a brief review. On the section on confidence intervals it says this: You can calculate a confidence interval with any level of confidence although the most common are 95% (z*=1.96), 90% (z*=1.65) and 99% (z*=2.58). This confused me a bit.
