wein AMBULANCE The difference between life and death is often just minutes when it comes to stopping bleeding. Two emergency procedures are being compared for their speed in stopping bleeding at the scene of accidents. The time from when 911 was called to the time that paramedics reported the bleeding stopped was recorded and sorted for a random sample of accidents. The data is shown below (in minutes). Procedure C-2: 3,4,4,5,6,6,7,7,7,8, 8, 8, 10, 14, 14, 15, 16, 17, 19, 19 checksum: 197 Procedure C-7: 8, 9, 10, 11, 11, 12, 12, 12, 13, 13, 13, 14, 14, 15, 16 checksum: 183 a. Determine if there is a difference between the population mean times it takes to stop the bleeding between the two procedures. b. What error (Type I or Type II) is possible from your analysis in part (a)? Is it likely and what would be the potential consequences or that error? c. Obviously a shorter average time would be an asset to either method. Name two other parameters that might be useful in evaluating these procedures and explain why they are useful
