Web7 de ago. de 2024 · To calculate the 95% confidence interval, we can simply plug the values into the formula. So for the USA, the lower and upper bounds of the 95% confidence interval are 34.02 and 35.98. So for the GB, the lower and upper bounds of the 95% confidence interval are 33.04 and 36.96. Webdimension, the simple density-based formula cannot be relied on. This occurs rarely, so we will not attempt to discuss general rules for generated conditional densities in this case.
