Question two In July 2020, during the vaccine rollout for the Covid-19 emergency, it was estimated that 90% of the population over 50 years old were fully vaccinated, while only 6% were completely unvaccinated. (The remaining 4% had only one dose or had an unknown vaccination status, and therefore will not be considered here.) A Public Health report on cases and hospitalisation from the "delta" variant was published at the end of July 2020. The report showed that, between February and July 2020, among the 418 people admitted to the hospital with the "delta" variant: - 163 were fully vaccinated - 136 were not vaccinated - The remaining people had only one dose or an unknown vaccination status and will not be considered here One may therefore wrongly conclude that a fully vaccinated person is surprisingly more likely to be hospitalised than an unvaccinated person. Using Bayes' theorem to calculate the relevant probabilities from the data above, prove that this claim is wrong. Show that this data actually proves that vaccines are extremely effective at reducing the risk of hospitalisation after contracting the "delta" variant
