Imagine that at the beginning of 2014, Boston and Los Angeles implemented a public health program that reduced deaths of infants less than 1 year old by 20 percent, while the cities of Honolulu and Indianapolis terminated an identical program. What would have been the approximate total impact of these program changes on the number of infant deaths in these cities?
A. There would have been 600 more deaths.
B. There would have been 70 more deaths.
C. There would have been 30 fewer deaths.
D. There would have been 65 fewer deaths.
E. There would have been 150 fewer deaths.

My least favorite type of question, how about you?
My estimates were 170 and 230 for Boston and LA before beginning the program, and 55 and 145 for Honolulu and Indy before ending the program. This is taken from the top graph using the lefthand axis and the darker bars.
We combine them to get 400 for Boston-LA and 200 for Honolulu-Indy. Now we just take 20 percent to get 80 fewer deaths expected for the following year in Boston-LA. Honolulu-Indy will lose its 20% benefit, so that means 200 is 80% of the expected figure. In other words, 200 = 4/5 x, so x is 250. that means we expect 50 more deaths there once the program ends. Kind of morbid question tbh.
The net effect will be 30 fewer deaths, so the answer is C.
PS Estimating stinks, but usually you will find that the numbers work out to something round and easy to work with. I could have estimated 175 and 235, which would have made this a bit harder. Pick numbers that both look reasonable and work out to round figures.
