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 is true about the cross products of a proportion?
They're equal

A statement that 2 ratios are equal?
A statement that two ratios are equal is called a proportion in math. An example of a proportion is 1/2 equals 2/4. In this proportion, if you cross multiply, you find that 4 x1 is equal to 2 x 2, which is a true statement or proportion.

How can you tell if a proportion is true?
If you cross-multiply and you obtain an equality, then the proportion is true. Example: 2/3 = 20/30 ? cross-multiply; 2 x 30 = 3 x 20 ? 60 = 60 Since we have an equality, the proportion is true.
What is true about the cross products of a proportion?

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 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.
