Data from "Statistical Inference "A famous medical experiment was conducted by Joseph Lister in the late 1800s. Mortality associated with surgery was quite high and Lister conjectured that the use of a disinfectant, carbolic acid, would help. Over a period of several years Lister performed 75 amputations with and without using carbolic acid." The segmented bar chart is given below. Which of the answer choices is the BEST initial guess? PATIENT DIED PATIENT LIVED PATIENT DRO PATINT LIVED O We cannot make an initial guess when there are only two bars present. The use of carbolic acid does not influence mortality. O The use of carbolic acid influences mortality.
