What is the question of this answer
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.

In determining safe speed of a vessel we must consider visibility, traffic density etc.
<h3>What is safe speed?</h3>
The safe speed of a vessel is the maximum speed the vessel can be operated to avoid hazards such as collision, damage of vessel, etc.
<h3>Factors considered when determining safe speed of vessels</h3>
In determining safe speed of a vessel we must consider the following factors such as;
- Weather condition, eg visibility
- Traffic density,
- Background light at night, etc
Thus, in determining safe speed of a vessel we must consider visibility, traffic density etc.
