4. OCEDA, an international health organization did a study that looked at the length of stay Covid-19 patients had in the USA and in Germany. Out of a sample of 100 patients selected at random in Germany, the average hospital length of stay of a patient was 7.5 days with a sample standard deviation of 1.2 days. Out of a sample of 49 patients selected at random in the USA, the average hospital length of stays was 5.5 days with a sample standard deviation of 2.0 days. The OCEDA want to test the null hypothesis that the countries have the same length of hospital stays. a.) State the Null and alternative Hypothesis. b.) What is the formula for the Test statistic? (You do not need to calculate) What are the values for each of the elements in this formula? [eg: n% = ; etc]
