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.

Parallelograms are shapes that have 4 sides, where the opposite sides are congruent and parallel
<h3>How to determine a parallelogram</h3>
For a shape to be a parallelogram, then the following must be true
- The opposite side lengths are congruent
- The opposite side lengths are parallel
- The diagonals bisect each other
<h3>The proof statement</h3>
The above statements in (a) above mean that:
The statements that prove that quadrilateral uwxy is a parallelogram are
- Diagonals UX and WY bisect each other
- Sides UW and XY are congruent
- Sides UW and XY are parallel.
