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.

I can personally say it changes your life & others around you. It will constantly make you have irrational thoughts and you won’t have a clear head space. Personally watching family go through that it’s never easy
I’m not 100% sure but I think it would probably be option (A)
Answer:
There are many ways you could answer this question.
Explanation:
If it is a physicl copy, you should store it with your other important doncuments of course, or have protective sheets on or around it for safety. If you are talking legally, a notarized document is always going to be more official that a non notarized document, so if you get it notarized, then you can protect yourself and the importance of the document legally.
