Question 1 9 points Save Answer Information was collected from a random sample of patients who had been admitted to an intensive care unit. The data collected is found in this file. After clicking on the link, click on "download" at the top. We are interested in the variables Systolic (systolic blood pressure in mm of Hg) and Service (Service = 0 means type of service was medical; Service = 1 means it was surgical.) We want to investigate whether there is evidence of a difference in systolic blood pressure between patients receiving a medical service and patients receiving a surgical service. There are 3 questions below, related to answering that question using a theoretical approach (methods of chapter 6) for the hypothesis test Ho: MM - Us = 0 and Hai HM - HS * 0 where AM = mean systolic blood pressure for all ICU patients receiving a medical service, and /is = mean systolic blood pressure for all ICU patients receiving a surgical service. You downloaded a dataset from the link provided above. Now upload it into the correct function in Statkey to give you the information you need to answer the three questions listed below: ALL of your answers to the questions below must appear together either on scrap paper or in the textbox below. If on scratch, label it with the heading "blood pressure". 1. (1 pt) Are the conditions met for using the theoretical approach (explain why or why not)? 2. (4 pts) Using the fact that the standard error is calculated to be 5.127, calculate the test statistic. (Round to 3 decimal places.) 3. (4 pts) Give the p-value (Round to 3 decimal places.) Supporting screen snip from Statkey must be pasted into your Word doc, under heading "blood pressure". For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
