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.
