Study 1. Most of the Covid-19 news cycle focuses on vaccines, but effective treatments have gotten less attention. Last year, some ER doctors reported success in treating Covid-19 using an experimental drug cocktail called Remdesnivir. The doctors who have used the drug cocktail saw anecdotal evidence that it can reduce hospital stays in those who have to be admitted for treatment. The CDC wants to assess the drug's efcacy before it can be recommended for emergency use, so they have you (and other statisticians at other hospitals) analyze the data on patient recovery (as measured by the number of days they spent in the hospital) before they report their ndings to the White House. The ER you have been tasked with sends you the data below. You correctly use a -tailed t test with an or level of .05 to determine whether Remdesnivir significantly reduces hospital stays or if the anecdotal effects noted by doctors are actually no more likely than chance. The patients who received Remdesnivir were released, on average, 11.2 days after being admitted to the hospital (SD : 1.41). The patients who received the placebo were released 15.8 days after being admitted to the hospital, on average (SD : 1.67). There were 29 participants in the Remdesnivir group and 31 in the control group. 1. What is the research hypothesis? 0 Remdesivir significantly reduces hospital stays 2. What is the null hypothesis? 0 Remdesivir will make no difference or signicantly increase hospital stays 3. What type of t-test would you use to see if there is a signicant difference? 4. How many tails will you be using in your calculation (Him: think about the researcher 's prediction). Following the appropriate steps, compute the t-test. 5. tcriricauazcsi: 6. t 2 value (dj): 7. p (circle): 8. a': 9.
