The conclusion of the research is that we reject the null hypothesis and we conclude that the bag filling machine does not work correctly at the 426 gram setting.
<h3>How to solve hypothesis testing?</h3>
We are given;
Population Mean; μ = 426
Sample mean; x' = 433
Sample size; n = 13
Standard deviation; s = 29
significance level; α = 0.05
Let us define the hypotheses;
Null Hypothesis; H₀: μ = 426 g
Alternative Hypothesis; H_a: μ < 426 g
Formula for the z-score here is;
z = (x' - μ)/(s/√n)
z = (433 - 426)/(29/√13)
z = 0.87
From online p-value from z-score calculator, we have;
p-value = 0.1922
This p-value is greater than the significance value and as such we reject the null hypothesis and we conclude that the bag filling machine does not work correctly at the 426 gram setting.

Originally, the SAT I was meant to test aptitude and the SAT II was meant to test achievement. That is to say, one tested what you were capable of and the other tested what you knew. But when the College Board moved away from the idea that the SAT I tests innate ability, they framed it as a reasoning test, making the difference between the two less defined.
With the latest changes, the SAT I (now just the SAT) is more focused than ever testing knowledge rather than logic. At this point, I would say that the SAT tests general knowledge and and the Subject Tests assess topical knowledge.

<h3>What is natural selection?</h3>
Natural selection is a term that refers to the evolutionary process that is based on the principle that establishes the survival of the fittest or the preponderance of the law of the strongest in a natural environment without external intervention.
In natural selection, the least fit or weakest individuals perish and their traits are not transmitted to the following generations by not reproducing.
According to the above, it can be inferred that the traits of the weak or less fit organisms studied four years earlier were not transmitted to the following generations, so the organisms studied by Losos four years later are not the same, but the offspring of The originals.
