Acompany advertises a mean lifespan of 1000 hours for a particular type of light bulb. if you were in charge of quality control at the factory, would you prefer that the standard deviation of the lifespans for the light bulbs be 5 hours or 50 hours? why?

I would prefer that the standard deviation of the lifespans for the light bulbs be 5 hours.

Explanation:

Standard Deviation is the square root of the sum of square of the distance of an observation from the mean. It is used to check the dispersion (scatter) in data.

Further, If Standard Deviation is 50 hours then the life of the bulb can be like 950 hours or 1050 hours. And if Standard Deviation is 5 hours then the life of the bulb can be like 995 hours or 1005 hours.

So there is a huge variation in the life of bulb if Standard Deviation is 50 hours.

Thus, I would prefer that the standard deviation of the lifespans for the light bulbs be 5 hours.

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !

there are no options provided but you can choose among the following gender-neutral pronouns: zir, hir, eir, vis, tem, eir.

in the normal course of maintaining a pronoun-antecedent agreement, we could have used the words his or her but since we are also required to use gender-neutral language, we need to replace it with its equivalent gender-neutral pronoun.
