If someone was hospitalized for the a virus does taking the medication significantly shorten the duration of the illness and therfore lower the number of days patients remain in hospital? Use the data below to calculate the relevant descriptive and inferential statistics to test the hypothesis that the durg shortens hospital stay. Without the medication the averrage duration was population mean=12 days, population standard deviation = 2 days Number of days in hospital while taking medication 13 10 8 12 11 9 13 1. What are the degrees of freedom in the study, df=? 2. What was standard error for patients taking the experimental medication? 3. What t(crit)-value must you exceed to reject Ho? 4. After doing the calculations, you find the t(obs) value to be? 5. What is the decision regarding the use of this drug to shorten hospital stay? Reject Ho or Fail to reject Ho
