It should be noted that the centers and variabilities that should be apparent in the distributions is that as the sample size increases, the variability of each sampling distribution decreases.
<h3>What is a sample size?</h3>
It should be noted that a sample size simply means the number if subjects that are talked into consideration from the entire population.
In this case, the centers and variabilities that should be apparent in the distributions is that as the sample size increases, the variability of each sampling distribution decreases. This was generated from the simulations.

Answer:
I dont understand what you are saying
The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
<h3>What is the litters about?</h3>
Note that:
We take x = volume of 25% solution.
We take y = volume of 65% solution.
So, Equation of total volume:
x + y = 80
Hence the equation of amount of acid:
0.25x + 0.65y = 0.45(80)
0.25x + 0.65y = 36
Solve x + y = 80 for x.
x = 80 - y
Then Substitute into the second equation.
0.25(80 - y) + 0.65y = 36
20 - 0.25y + 0.65y = 36
0.4y = 16
y = 40
x + y = 80
x + 40 = 80
x = 40
Therefore, The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
