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.

Given information: The sample mean of total cases is x-bar = 1715145. The sample size is n = 25 The…

Consider the time it takes, in minutes, for police officers to respond to a 911 call, where a life-threatening crime (an armed robbery, an assault, a shooting) is in progress. For a particular police jurisdiction, the average response time is 25 minutes with a standard deviation of 3 minutes. Assuming the data is symmetric and using the Empirical rule, what %% of the response times fall between 19 to 31 minutes. __68% __99.7% ___95% __86% __50% ___none of above
A researcher is interested in investigating whether religious affiliation and the brand of sneakers that people wear are associated. The table below shows the results of a survey.
