Answer:
Alternative explanation for observed result
Explanation:
The alternative explanation for observed result is used during investigation process and also used to rule out doubts and the probability of considering other reasons for the identified or observed outcomes. However, alternative explanations should be considered in all outcome evaluations, whether formally or informally. It should be added to the conclusion part or section of a research poster or research report.
The percentage of occupational therapists that earn more per year than Ginny is equal to 99.87%.
<h3>How to determine the percentage?</h3>
In order to determine the percentage of occupational therapists that earn more per year than Ginny, we would calculate the z-score by using the following formula:
Z = (x - u)/σ
<u>Where:</u>
- σ is the standard deviation.
Substituting the given parameters into the formula, we have;
Z = (44,000 - 65,000)/7,000
Z = -3.
For the p-value:
P(x > 44,000) = P(Z > -3) = P(Z < 3)
P(Z < 3) = P(Z = -3)
P(Z = -3) = 0.4987
P = 0.4987 + 0.5
P = 0.9987
Therefore, percentage = 99.87%.

Explanation:
Brass is a metal alloy that is always made with a combination of copper and zinc. By varying the amount of copper and zinc, brass can be made harder or softer. Other metals—such as aluminum, lead, and arsenic—may be used as alloying agents to improve machinability and corrosion resistance.
