### Statistical Analysis of Vacation Days According to a travel website, workers in a certain country lead the world in vacation days, averaging 22.91 days per year. The following data show the number of paid vacation days for a random sample of 20 workers from this country: - **Vacation Days:** 9, 6, 8, 10, 18, 22, 23, 23, 34, 65, 23, 25, 20, 23, 30, 29, 32, 23, 26, 35 #### Analysis Question: **b. Do the results from this sample validate the website's findings?** **Options:** - **A.** Since the population mean, 22.91, is contained within the 95% confidence interval, it can be said with 95% confidence that the sample does **not validate** the website's findings. - **B.** Since the population mean, 22.91, is contained within the 95% confidence interval, it can be said with 95% confidence that the sample **validates** the website's findings. - **C.** Since the population mean, 22.91, is **not** contained within the 95% confidence interval, it can be said with 95% confidence that the sample does **not validate** the website's findings. - **D.** Since the population mean, 22.91, is **not** contained within the 95% confidence interval, it can be said with 95% confidence that the sample **validates** the website's findings. **Answer:** - **Option B** is selected: The population mean, 22.91, is contained within the 95% confidence interval, confirming the sample validates the website's findings with 95% confidence.
