Suppose that 15% of the 1750 students at a school have experienced extreme levels of stress during the past month. A high school newspaper doesn't know this figure, but they are curious what it is, so they
decide to ask a simple random sample of 160 students if they have experienced extreme levels of stress
during the past month. Subsequently, they find that 10% of the sample replied “yes to the question.
Assuming the true proportion is 15%, what is the approximate probability that more than 10% of the
sample would report that they experienced extreme levels of stress during the past month?

(23*2)-12=x     x=34

step-by-step explanation:

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
