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.

Answer:
Alexander Hamilton chose party over principle and attempted to ride the Federalist secessionist wave back into power.
Explanation:
<span>Members lifted weights: W=32%
</span><span>Members preferred aerobics: A=41%
</span>Members preferred both: B=6%
Members lifted weights only: Wo=W-B=32%-6%→Wo=26%
Members preferred aerobics only: Ao=A-B=41%-6%→Ao=35%
F<span>ind the probability that the member prefers another method neither weights nor aerobics to exercise: N=?
N=100%-Wo-Ao-B
N=100%-26%-35%-6%
N=100%-67%
N=33%
Answer: T</span>he probability that the member prefers another method neither weights nor aerobics to exercise is 33%
