Ind the average caffeine intake of the group to be 273 mg/day. A 99% confidence interval for the average daily caffeine intake was found to be (265.73 mg/day, 280.27 mg/day). Which of the following is a correct interpretation of the 99% confidence level? We are 99% confident that the sample mean caffeine intake is between 265.73 mg/day and 280.27 mg/day. We cannot interpret the confidence level in this case because the sample size is not very large. Therefore this estimate is not likely to accurately reflect a plausible set of values for the population of interest. There is a 99% probability that the population mean caffeine intake is between 265.73 mg/day and 280.27 mg/day. O If we were to take every sample of size 28, then 99% of the intervals created would capture the sample mean caffeine intake for this population. frize 28 then 99% of the intervals created
