Based on interviews with 88 SARS patients, researchers found that the mean incubation period was 5.1 days, with a standard deviation of 14.4 days. Based on this information, construct a 95%

confidence interval for the mean incubation period of the SARS virus. Interpret the interval.

The lower bound is ___days. (Round to two decimal places as needed.)

The upper bound is ___days. (Round to two decimal places as needed.)

Interpret the interval. Choose the correct answer below.

.AThere is a 95% probability that the mean incubation period lies between the lower and upper bounds of the interval

OB. There is 95% confidence that the mean incubation period is greater than the upper bound of the interval

C. There is 95% confidence that the mean incubation period lies between the lower and upper bounds of the interval

D. There is 95% confidence that the mean incubation period is less than the lower bound of the interval
