STATS 10 Lecture Notes - Lecture 4: Streptomycin, Random Assignment
Document Summary
Question 1: summarize the results of hill"s study. a. ) Justify your answer: we can see that 51 out of 55 in the treatment group received the streptomycin recovered. 38 out of 52 people recovered, of the people in the control group who received only bed rest. It is clear that the people in the treatment group are more likely to recover, from summary table. It seems like the people are dependent and therefore streptomycin is an effective treatment. If both the treatment and outcome were independent we would be able to expect about 18 people to die: we would expect about 9 people to die in the streptomycin group. 0. 168 x 55 (people in streptomycin group) equals the total people who would die if treatment and outcome were independent. Question 3: design and execute an appropriate simulation in fathom using a chance model to replicate hill"s study under the assumption that treatment and outcome are independent.
