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.

The action that will contaminate the field is; Extending your arm over the sterile field to pour the liquid into the receptacle.
<h3>How to add to a sterile field?</h3>
Sterile fields are areas that are set up for procedures are made sure to be free of microorganisms. Usually, a tray covered with a small towel. The tray contains equipment and supplies for the procedure.
Sterile field also refers to a section area that is set apart in order to place sterile surgical drapes on the patient's surgical site and also on the stand that will hold in place the sterile instruments and other items needed during surgery.
The purpose of the sterile field is to minimize the population of microbes.
Therefore, we can ensure proper maintenance of a Sterile field by remaining in the operating room at all times and avoiding leaning on tables.
Finally, when adding a sterile liquid to a sterile field, the action that will contaminate the field is Extending your arm over the sterile field to pour the liquid into the receptacle.
