Question

Based on interviews with 96 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 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. O A. There is 95% confidence 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. O C. There is 95% confidence that the mean incubation period is less than the lower bound of the interval. OD. There is a 95% probability that the mean incubation period lies between the lower and upper bounds of the interval. Click to select your answer(s).

Answer 1

As we SARS have given total sample size (n) = 96. Patients. researchers found that the incubation period (7) 5 day, with standard mean deviation T = 15.4. As we know formula for confidence interval of population mean (e) [ mean incubation period) X I 1.96x ( 57 1.96x15.4 9.79 [ 5 3.08 ] [ 1.92, 8.08 ] = 1.92 lower bound (L) upper bound (U) = 8.08 Interpretation: option is correct. to the - because a Confidence interval refors kolm parameter will fall two get values for ceritain proportion of times, probability that a between canned with CamScanner
