Most students get this SAT statistics question wrong..

[00:00:00]Most SAT students get this wrong. Can you solve it? A health organization randomly surveyed 1,200 teenagers and asked each teenager, "Do you exercise for at least 30 minutes per day?" 64% reported that they did. Which of the following statements must be true? 1 2 or three? I know this is the ugliest mother freaking thing to look at, but don't be scared away by these. You just go peace meal and they're pretty simple.

[00:00:23]Let's completely ignore the answer choices and just validate or invalidate each statement with a check mark. One, of all teenagers in the school district, 64% exercise for at least 30 minutes per day. All really, we had a survey of 1,200 students and 64% of them exercise this much. That's one sample, not all students. Kill it. Two. If another 1,200 teens selected at random from the same district were surveyed, 64% of them would report the same thing. So, you're telling me that in our first survey, exactly 768 kids said they exercise? If we ask a whole new group of 1,200, exactly 768 would say the same thing.

[00:01:03]Not like 764 or 300. Then get out of here, too. Last one. Three. If 1,200 teens from a different school were surveyed, 64% of them would report they exercise. Bro, that's the same ridiculous idea as number two. It's a different group of people. The answer is none of these. Want more SAT hacks?
