The correct answers! I'm going to go back and unscreen all the guesses to the earlier questions in a minute, but here are the correct answers:
The first three questions are all about seeing an answer that the question tries to suggest, which is wrong, and rejecting it. MOST people got these right.
1. A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost?
Suggested answer: $0.10. Correct answer: $0.05. The ball costs $0.05, thus the bat costs $1 more ($1.05), thus the combination costs $1.10
2. If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?
Suggested answer: 5/5/5 becomes 100/100/100! Correct answer: 5 minutes. It takes ONE machine 5 minutes to make ONE widget. Running 100 machines at once means each takes 5 minutes, so your total time to make 100 widgets is... 5 minutes.
3. In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?
Suggested answer: half the time! Correct answer: 47 days. It doubles each day, therefore if it's covered 100% on day 48, it's covered 50% on day 47.
The fourth question is a little trickier, and far fewer people got it right. It's about the problem of small samples.
4. A certain town is served by two hospitals. In the larger hospital about 45 babies are born each day, and in the smaller hospital about 15 babies are born each day. As you know, about 50% of all babies are boys. However, the exact percentage varies from day to day. Sometimes it may be higher than 50%, sometimes lower. For a period of 1 year, each hospital recorded the days on which more than 60% of the babies born were boys. Which hospital do you think recorded more such days?
a)The larger hospital b)The smaller hospital c) About the same (that is, within 5% of each other)
Here, C) is the obvious answer: The same babies are being born! Why would the numbers be different? Well, that's wrong.
I don't think anyone guessed A, but the rest of the guesses were split between B and C. The correct answer is B, because the smaller sample size means that it takes fewer anomalies to deliver an outsidethenormal result.
In the smaller hospital, 15 babies are born each day. Assuming ~50% boys (as the question does), you expect 7.5 boys per day. "60% boys" is only 9/15  you only need the 0.5 to go boy (which it will do on 50% of days) and ONE other coin flip to go boys for that hospital to hit 60% boys for a day. I'll spare you the math, but that should happen 30.4% of the time. Here's a chart:
In the LARGER hospital, 45 babies are born each day. Assuming ~50% boys, you expect 22.5 boys per day. "60% boys" is 27/45  you need the swing baby and FOUR more babies for that hospital to hit 60% boys on a day. Again, math skipped for the overview, but that's about 11.6%. Chart:
So, the small hospital, in the course of a year, expects about a hundred and ten "60% or more boys" days. The large hospital only expects 40ish.
For the record, I find it SUPER INTERESTING that on question 4, nobody said A. Not even as a "random guess".

Old questions are often fun. A trio of very old but still very neat questions.
1. A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost? 2. If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?
3. In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?
Responses screened, initially!
ETA: Ooh, a 4th.
4. A certain town is served by two hospitals. In the larger hospital about 45 babies are born each day, and in the smaller hospital about 15 babies are born each day. As you know, about 50% of all babies are boys. However, the exact percentage varies from day to day. Sometimes it may be higher than 50%, sometimes lower. For a period of 1 year, each hospital recorded the days on which more than 60% of the babies born were boys. Which hospital do you think recorded more such days?
a)The larger hospital b)The smaller hospital c) About the same (that is, within 5% of each other)
EDIT: OKAY IT'S BEEN 14 HOURS. ANSWERS ARE UP. Feel free to guess if you haven't read the answers yet.
