statistics

j3ssvern:

a recent Harris Poll survey of 1010 U.S. adults selected at random showed that 627 consider the occupation of firefighter to have a very great prestige. Estimate the probability (to the nearest hundred) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige

The fraction of adults who think the occupation of firefighter is prestigious is 627/1010

I suspect that to the nearest hundredth was intended, which would then be 0.62.

Yes, that makes a lot more sense!

What is the probability that a *marginally proficient* tutor in most maths will s***w up an answer to a statistics question? Hint: It is proportional to and higher than a student posting a coherent question with one typographical error.

The typographical error (missing "th") is obvious because the request is for probability. Probability is a value from 0 to 1. Extending the question to a numerical population requires more advanced maths than calculating a frequency mean as a percentage of two numbers.

Does anyone know how to do that?

Of more importance is obtaining a correct demographic for the population in question. That is the easy part. There are at least 3 web sites give that information. The value 186237600 is not even close (That value is close to the speed of light in miles per second when the light passes through a brain fog, so it does have some relevance). If you are going to extend the question, you should answer it with a little care, even if you don't know how to do it properly.

Here are some statically relevant questions.

What is the probability of a firefighter possessing the skills for determining the cause of a fire?

Answer. It is about the same as a general mathematician possessing the skills for statistical mathematics. Very close to zero.

What is the probability that "I like Serena" will make a comment on a question that either states the obvious or is trivial and useless.

Answer. It is still in a dynamic state, but is approaching very close to 1 to the nearest hundredth.

Statistically Irreverent but not Irrelevant.

My preferred mode of operation is to state the obvious, which then leads to ooh and aah - now I understand!
This is usually how mathematics works: once you see it, it is obvious and in retrospect you can't understand why you didn't see it before.
Ah well, often it helps if someone points out the obvious.

Are you sure they are not saying "I understand" just to shut you up? That is "Shut your Pi hole" in math speak.

Your "preferred mode of operation is to state the obvious?" Statistically, your preferred mode of operation is to post "stamps of approval" like a tomcat spraying his territory. This is now obvious and in retrospect you can't understand why you didn't see it before.

Your tomcat behavior indicates, obviously, you are a late teenage to early 20s male.
But on this post http://web2.0calc.com/questions/ap-stat-please-help
you say, "If you register with this link, you'll give me a brownie point."

A brownie is a member of an organization for preteen girls. This is very confusing (not obvious). So maybe you are a preteen girl. The Professional Troll Association rules forbid trolling young children. If it is just your wish then the rules are not applicable.
