Based on interviews with 84 SARS​ patients, researchers found that the mean incubation period was 5 ​days, with a standard deviation of 15.4 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 nothing days.​ (Round to two decimal places as​ needed.) The upper bound is nothing days. ​(Round to two decimal places as​ needed.) Interpret the interval. Choose the correct answer below. A. There is a​ 95% probability that the mean incubation period lies between the lower and upper bounds of the interval. B. There is​ 95% confidence that the mean incubation period is less than the lower 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 greater than the upper bound of the interval.

Given :-

Mean () = 5

Standard deviation (Sx) = 15.4

Sample size (n) = 84

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

Lower limit = 1.658,

Upper limit = 8.342
