Question
**Text Transcription:** Assume the values given below are based on the data for the largest 25 WHO countries. Treat this as a sample of the world population (e.g., n = 25). Develop a 95% confidence interval for Total Cases in cells C17-C21. | | Population | Total Cases | |------------------------|---------------|--------------| | \(\bar{x}\) = | 231,113,523 | 1,715,145 | | n = | 25 | 25 | | s = | 361,793,995 | 3,167,626 | | Confidence Coeff. | 0.95 | 0.95 | | Significance Level (α) | 0.05 | 0.05 | - \(t_{α/2} =\) - MOE \(t_{α/2}*s/\sqrt{n} =\) - MOE CONFIDENCE.T Total Cases Interval Note, s is larger than μ. Please explain how this can be. 1) **Explanation of Content:** The table presents a scenario involving data from the largest 25 WHO countries to compute a 95% confidence interval for total cases. The columns include information for population and total cases, like mean (\(\bar{x}\)), sample size (n), standard deviation (s), confidence coefficient, and significance level (α). The formula for the margin of error (MOE) is provided but not completed in the sheet, indicating it's necessary for calculating the confidence interval. The task is left open-ended for calculating \(t_{α/2}\) and the margin of error. The note on the right states: "Note, s is larger than μ. Please explain how this can be." This prompts an explanation of how the standard deviation (s) could be larger than the mean (μ), which may occur in datasets with large variability or outliers. The layout doesn’t include graphs or diagrams.
