Infection Risk

  The 43,661 subjects were split evenly between the placebo and vaccine groups (about 21,830 subjects per group). In the placebo group — the group that got a 'fake'. vaccine— 162 became infected with the coronavirus and showed symptoms. In the vaccine group — the group that got the real vaccine — that number was only eight. In your project reporb include the following table to store these numbers and your calculations: Gioup Group size Number Infected infection Risk Placebo 21,830 162 Vaccine 21,830 8 Answer the following questions (and fill in the corresponding table cells): • What percentage of the placebo subjects became infected? • What percentage of the vaccine subjects became infected? • These numbers are each group's Infection risk:. Put these numbers in the appropriate places of the Infection risk" column. (At the bottom of this page is a link where you can check your work.) • Both infection risks am lower than 1 percent. Would you describe the placebo and the vaccine infection risks as low or high? Explain. • Is the vaccine group's infection risk that different erent from the placebo group's? Explain. Scale Up: It can be hard to see a vaccine's impact in terms of percentages. Let's answer the same questions as above after calculating what the infection risks indicated by Pfizer's study would look like if applied to the entire population of the United States. Answer the following questions (and fill in the corresponding table cells):
