Prof Rea’s Exam Q3 Vaccine researchers want to know which Covid-19 vaccine result in higher rates of side effects after the second dose. They randomly survey 200 people who got the Pfizer vaccine, and 189 people who got the Moderna vaccine. Of those who had the Pfizer vaccine, 28 reported mild to severe side effects the day after receiving the second dose. Of those who had the Moderna vaccine, 21 reported mild to severe side effects the day after receiving the second dose. The researchers will test the claim that the second dose of the Pfizer vaccine results in a higher rate of side effects than the second dose of the Moderna vaccine at a 1% level of significance. Round all calculated values to three decimal places. Show all steps of a hypothesis test to earn full credit.
