A hospital trialling a new anaesthetic has collected data on how long the new and old drugs take before the patient becomes unconscious. They wish to know which drug acts faster and which is more predictable.
*Old drug times (s):* 8, 12, 9, 8, 16, 10, 14, 7, 5, 21, 13, 10, 8, 10, 11, 8, 11, 9, 11, 14
*New drug times (s):* 8, 12, 7, 8, 12, 11, 9, 8, 10, 8, 10, 9, 12, 8, 8, 7, 10, 7, 9, 9
Draw a parallel box plot for the data sets and use it to compare the two drugs.
