Based on interviews with 81SARS patients, researchers found that the mean incubation period was 5.8 days, with a standard deviation of 15.9 days. Based on this information, construct a 95% confidence interval for the mean incubation period of the SARS virus. Interpret the interval.
1.The lower bound is
days. (Round to two decimal places as needed.)
2. Determine the upper bound, rounding to two decimal places.
