Expected Value 9. The standard error calculation can be done by the mathematical formula SE = (√((p(1-p)/n) )). Confidence Intervals - Finding Sample Size - Διάρκεια: 8:46. Learn more You're viewing YouTube in Greek.

Otherwise, we use the t statistics, unless the sample size is small and the underlying distribution is not normal. If the population standard deviation is unknown, use the t statistic. As a rough guide, many statisticians say that a sample size of 30 is large enough when the population distribution is bell-shaped. All Rights Reserved.

Another approach focuses on sample size. For example, if your CV is 1.95 and your SE is 0.019, then: 1.95 * 0.019 = 0.03705 Sample question: 900 students were surveyed and had an average GPA of 2.7 Find Confidence Interval 2. show more I've found both of those things before on the calculator but I was given additional information in the problem.
