The reason why the number of failures and successes in two population proportions must be up to 10 is because it is important to have many of samples from both populations.
<h3>What is a Confidence Interval?
</h3>
This refers to the probability displayed that a parameter will exist between a pair of values around the mean.
It measures the extent to which one can be certain or uncertain about ones sampling method. Confidence Intervals are usually constructed using levels of 95% or 99%.

So the fraction would be 13/100 so now divide it and then u should get 7.6923076923
ANSWER
The required equation is:

EXPLANATION
The given equation is

Dividing through by 225 we obtain;

This is a hyperbola that has it's centre at the origin.
If this hyperbola is translated so that its center is now at (0,5).
Then its equation becomes:

We multiply through by 225 to get;

We now expand to get;


The equation of the hyperbola in general form is

Answer: The answer is 3.77.
Explanation: Since 0.10 is 10 times smaller than 1, we know that if we divide 37.7 by 10, we will get the same answer as 0.10 x 37.7.
