Question 2 A study investigated the recovery period for COVID-19 patients in two different countries namely Country 1 and Country 2. Researchers tested the claim that average recovery period (in days) in Country 1 is longer than Country 2 at 1% significance level using random samples of 10000 patients in Country 1 and 7500 patients in county 2 who have recovered a) Conduct the hypothesis testing procedure using critical value approach and interpret your result(Manual Solution). b) Validate your result in part a) manually using R (Use p-value approach). (Manual Computation) c) Using the relevant predefined functions, validate your answer in parts a and b by applying both critical value and p-value approaches.
