Calculate the probability that the sample variance of a random sample of size n 5 from a Normal population with σeq2 eq 25 will be between 20 and 30. The other important piece of information is the confidence level required which is the probability that the confidence interval contains the true point estimate. Its an online statistics and probability tool requires confidence level confidence interval and the population proportion to determine sample size to perform t-test anova test etc.
