<h3 /><h3>What were crude stone tool?</h3>
Any tool that is partially or totally fashioned out of stone is considered a stone tool in the broadest definition. Even if there are still societies and cultures that rely on stone tools, most of them are related to extinct prehistoric (especially Stone Age) cultures.
Archaeologists frequently research these prehistoric societies, and the examination of stone tools is known as lithic analysis. To deepen our understanding of the cultural ramifications of stone tool use and production, ethnoarchaeology has been a useful research field.
Arrowheads, spearheads, hand axes, and querns are just a few examples of the numerous tools made from stone throughout history. Stone can be ground into tools or it can be shaped by a flintknapper into knapped implements.

Answer:
D) generates the highest contribution margin per stamping machine hour
Explanation:
Since the stamping machine is Kinsi's constrained resource, or bottleneck resource, in order to maximize its profit, the company should manufacture the products that maximize the utility of the stamping machine. The product that maximize the utility are the one that have the highest contribution margin. Therefore Kinsi must produce the products that have the highest contribution margin per stamping machine hour.
Answer: parametric
Explanation:
As a general rule of thumb, when the dependent variable’s level of measurement is nominal (categorical) or ordinal, then a non-parametric test should be selected. When the dependent variable is measured on a continuous scale, then a parametric test should typically be selected. Fortunately, the most frequently used parametric analyses have non-parametric counterparts. This can be useful when the assumptions of a parametric test are violated because you can choose the non-parametric alternative as a backup analysis.
