The pooled sample proportion requires two samples combined to estimate the single p instead of estimating p1 and p2 separately. Therefore, it's true.
<h3>What is a pooled sample?</h3>
It should be noted that the pooled sample of a proportion is the weighted average of the proportion from the two samples.
In this case, the combined pool sample is called the poooled sample proportion and it's used in expression of the standard error.
In conclusion, the correct option is true.

Answer:
Overall answer: 10 1/9 - 1 5/18x (Most simplified answer)
Step-by-step explanation:
First you have to do all the Distributive property which the answer would be:
2 1/2 - 1/2x + 3 1/9 + 8/9x + 1/6x - 5/18x + 2 14/18 + 1 13/18
Then you have to find the common demoninator which would be 18
After that you have to put them in the correct order since there is two different terms which would be:
2 9/18 + 3 2/18 + 2 14/18 + 1 13/18 - 9/18x + 16/18x + 3/18x - 5/18x
After that you solve the problem which in the end after solving both terms it ends up as..:
10 2/18 - 1 5/18x
and I think that is as simplified as you can go term wise.
I hope this helps and I hope I didn't make a mistake :D
First, find your "zeroes". We know that the denominator cannot equal 0 so
x² ≠ 0 → x ≠ 0
Next, multiply both sides by x² to clear the denominator (since x² will always be positive, the inequality sign will not change). This leaves you with:
|x + 2| - |x - 3| > -x²
Change the inequality symbol to an equal sign and solve for all possibilities: (x+2) - (x-3) = -x² → imaginary number
(x+2) - -(x-3) = -x² → x = -1 + √2, x = -1 - √2
-(x+2) - (x-3) = -x² → x = 1
-(x-2) - -(x-3) = -x² → x = √5, x = -√5
Now, find Test Points between all of the values above to see which makes a TRUE statement with the original inequality.
Answer: x < -√5 or x > -1 + √2
