My friend and I have begun work on a folding at home statistics site.
I'm going to break F@H down for you all real quick.
Every 3 hours a Team submits more points and "Units" to their total points and Unit count. (The unit is where the points come from). So every 3 hours Point and Unit...
I only had the quiz directions to go on during the quiz.
Also, the teachers answer, "The student was speaking nonsense." Is not necessarily true even given his interpretation, or so it would seem.
The student could in fact be correct if the true ratio of red to non-red was equal to or...
Ok, fair enough, I agree with all of that. This is why I said it comes down to interpreting what the friend actually meant within the problem. I understood it as prior probability and that is why I took issue, obviously my interpretation could be wrong, though arguably the question was...
I never said my teacher is wrong. I asked if he was.
I don't think this has come down to an issue of reasoning but rather interpretation of the wording of the problem.
Secondly, I fully understand where you are coming from. I just don't agree with your interpretation of what the student...
Ok, but you would be foolish to assert that the probability of picking a red is certainly 10% prior to opening the bag.
Now if I have watched in desperation as you have tried and failed to pick a red M&M from the bag and I say "Don't worry, you have increased your chances of picking a red...
It wouldn't matter if either were the case.
In the end, the %'s given at the start are irrelevant. P(picking red) = N(number of reds) / D (number of total M&M's) The friend isn't assuming factory percentages are actually the case within the bag but rather that probability has changed from...
Ah I see what you are taking issue with.
OK, you are right that the bag could come with a 7% count of red. But that is understood, the question is not "will the probability be greater then 10%" But, "will the probability be greater then it was before you drew any out of the bag, w/e that %...
I'm only assuming that the percentages are reasonably accurate. In the end, the percentages are irrelevant. It wouldn't matter if my bag was largely off the production mean. You can substitute any non-zero number for N and the probability will ALWAYS increase as long as D is greater then 10...
I am a student in an Intro. Stat. class at a local community college.
I recently got a quiz back in which the teacher marked me wrong and upon questioning with more explicit detail he still told me I was wrong.
The question:
1) The Masterfoods company manufactures bags of Peanuts Butter...
