Question 5 Blood cocaine concentration (mg/L) was determined both for a sample of individuals who had died from cocaineinduced excited delirium (ED) and for a sample of those who had died from a cocaine overdose without excited delirium; survival time for people in both groups was at most 6 hours. ED: NON-ED : nunmnmmm-m mmmmmn 225.5.- 25.5 (a) Determine the threequartile values for blood cocaine concentration for both ED and NonED samples. (b) Construct a comparative boxplot (two boxplots on the same set of axes, one above the other) (c) Describe (Compare and Contrast) the ED and Non-ED samples in your own words from the boxplot
