Remember, you can do anything to an equation as long as you do it to both sides
and when multiply or divide by a negative in inequalities, flip the direction of the sign
12x-39<9
add 39 to both sides
12x<48
divde bothh sides by 12
x<4
-4x+3<-6
minus 3 both sides
-4x<-9
times both sides by -1 and flip sign
4x>9
divide both sides by 4
x>9/4
Answer:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
Step-by-step explanation:
A confidence interval of a proportion p% at the x% level with m% margin of error means that:
We are x% sure that the true mean of the population is in the interval from (p-x)% to (p+x)%.
In this problem, we have that
90% confidence level
44% with a margin of error of 2%
So:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
