Question 9 (1 point) A national study estimated that the average incubation period of COVID-19 is 5.08 days. Let's assume that the incubation period follows a normal distribution, with standard deviation of 0.31 days. (Source: He, W, Yi, G Y, Zhu, Y. Estimation of the basic reproduction number, average incubation time, asymptomatic infection rate, and case fatality rate for COVID-19: Meta-analysis and sensitivity analysis. J Med Virol. 2020; 92: 2543 2550. https://doi.org/10. 1002/jmv.26041) If we take a sample of 200 people locally with COVlD-19, what will the expected value for the average number of days of the incubation period be for this sample? 0 I need more information to answer this. Question 10 (2 points) A national study estimated that the average incubation period of COVlD-19 is 5.08 days.
