WebTranscript. If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate. More precisely, it's actually 1.96 standard errors. This is called a critical value (z*). We can calculate a critical value z* for any given confidence level using normal distribution calculations. WebFeb 28, 2024 · The Z-Score has been calculated for the first value. It is 0.15945 standard deviations below the mean. To check the results, you can multiply the standard deviation by this result (6.271629 * -0.15945) and check that the result is equal to the difference between the value and the mean (499-500). Both results are equal, so the value makes sense.
