IL-6 is a cytokine released as an immune response to infection. Elevated IL-6 is suggested to be predictive of severe illness with Covid-19. Suppose we wanted to conduct a study to see if this is true among patients with Covid-19 in Florida. Assuming from a previous studies in other areas of the US, the mean IL-6 id 8.13 pg/mL (s.d.= 5.98 pg/mL) among individuals with moderate disease and 7.66 pg/mL (s.d.= 4,97 pg/mL) among individuals that are asymptomatic or have mild illiness, how many people ,in total, would need to enroll in our new study to determine if there is a difference in means with 99% confidence and 80% power? A. 942 B. 1,212 C 1.054 D. 1,650
