Question
According to a travel website, workers in a certain country lead the world in vacation days, averaging 25.55 days per year. The following data show the number of paid vacation days for a random sample of 20 workers from this country. Complete parts a through see below. **Round to two decimal places as needed.**
Acdng toael w wotes ina cetain country lead the world in vacation days, averaging 25 55 days per year The following data show the number of paid vacation days for a random sample of 20 workers fom this country Complete parts a through c below 27 63 Contruta95% conidence interval to estimate the average number of paid vacation days for workers from this country The 5% conddence terval to estimate the average number of paid vacation days for workers from this country is from days todays Rand to decimal places as needed) De the ress rom this sample validate the website's finding? OA Since the population mean, 25 55, is not contained within the 95% confidence interval, t can be said with 9W% confidence that the sample does not validate the wobs's findings OR Since the population mean, 25 55, is contained within the 95% condidence interval, can be said with 95% confidence that the sample does not validate the webs's findings OC Since the population mean, 25 55, is contained within the S5% confidence interval, it can be said with 95% confidence that the sample valdates the webs's findings OD. Since the population mean, 25 55, is not contained within the 95% condidence interval t can be said with 9s% confidence that the sample validates the webst's findings What assumptions need to be made about this population? OA The only assumption needed is that the population distribution is approimately normal OB The only assumption needed is that the population standard deviation is known OC. The only assumption needed is that the population distribution is approximately uniform OD. No assumptions are requdred
