What does a 95 percent confidence interval tell you about the population proportion?
There is a 95% probability that the true population proportion lies within the confidence interval.
Arrange the four numbers to form proportion that is true?

What are 2 ways you can tell that 2 ratios form a proportion?
what are 2 ways you can tell that 2 ratios from a propotion
What do you know about direct proportion and inverse proportion?
direct proportion: y=kx inverse proportion: y=k/x
Are two quantities that form a proportion proportional?
Yes, they are in the proportion of the proportion that they form!
How can you tell if a proportion is false?
Multiply the cross products, and see if they are equal. If they are equal, the proportion is true. If they are unequal, the proportion is false.
What does a 95 percent confidence interval tell you about the population proportion?

Is this a true proportion 25 75 equals 9 27?
Yes the proportion for them both is 1:3
What is true about the cross products of a proportion?
They're equal
How do you tell a proportion is true?
You appear to be referring to the fact that if a/b = c/d then ad = bc. You know this is true because of the axioms of equality (If you do the same thing to both sides of an equation, then equality is maintained). a/b = c/d multiply by d ad/b = c multiply by b ad = bc If you wish to prove a specific proportion is true, you can test it with the equation ad = bc
Total variable cost does not increase in proportion to output is it true?
False, it is the fixed cost which is not increased or decreased with proportion to output.

What is a true proportion?
A true proportion is when two ratios are equal to one another. To prove this, you need to find the cross products of the ratios and see if they are equal. An example of a true proportion are the ratios 1/2 and 5/10, if you take the cross product the result is 2 x 5 = 1 x 10, which are equal.
What is difference between proportion and probability?
Proportion is the probability of a selected sample. probability is the true probability of all cases. If this is not what you are looking for then please specify.
