Additional homework problem:
Submit your solution to the following along with your
solutions to the problems from the text:
There are two hospitals named Mercy and Hope in your town.
You must choose one of
these in which to undergo an operation. You decide to base your
decision on the success of their surgical teams.
Fortunately, under the new health plan the hospitals
give data on the success of their operations,
broken down into five broad categories of operations.
Suppose you get the following data for the two hospitals:
Type A B C D E All
Operations 359 1836 299 2086 149 4729
Successful 292 1449 178 434 13 2366
Rate .81 .79 .60 .21 .09 .50
Type A B C D E All
Operations 88 514 222 86 45 955
Successful 70 391 113 12 2 588
Rate .80 .76 .51 .14 .04 .62
You notice that, in all types of operations, Mercy Hospital has a
higher success rate than Hope Hospital and yet Hope has the highest
overall success rate. Which hospital would you choose and why?

You can often use the default source type of "Major World Publications", but sometimes
need to add Magazines to that--you can just choose "All News" as well.
Possible essay questions:
- Describe two of the examples discussed in the article in which WEIRD
subjects were found to respond differently from other
subjects? Formulate another example question where there might
be such a difference. Explain.
- If you were a psychology professor designing a study,
how might you correct for the fact that most of your
subjects are probably WEIRD? Would the question you were
studying make a difference?
