95 Confidence Interval Sample Size. If repeated samples were taken and the 95 confidence interval computed for each sample 95 of the intervals would contain the population mean. The confidence level is 95.
Because the sample size is small we must now use the confidence interval formula that involves t rather than Z. StatKey was used to construct a 95 confidence interval using the percentile method. Feb 18 2018 The confidence interval can take any number of probabilities with the most common being 95 or 99.
Assuming the following with a confidence level of 95.
Population standard deviation σ 5 σ 5. The confidence is. The t value for 95 confidence with df 9 is t 2262. Feb 18 2018 The confidence interval can take any number of probabilities with the most common being 95 or 99.
