Since you guys arent very smart im going to predict that your chances of getting this right is about the same as guessing. so about 3/4 of you will give the wrong answer.

B

0.1%

B. Affecting a very small part of the population doesn't change the test's accuracy.

coronavirus was made up by jews to control the masses.
so 95%

it says you test positive in big red letters you fucking retards so the answer is 100%
based

This

I guess i overestimated you guys, so far its 0 right answers.

0/5

>The test is 95% accurate

.095 probability

Explain

the test is 95% accurate so theres a 5% chance of a false positive
you fucking retard

Not enough information to be sure. A test can be 95% accurate by sometimes giving a false negative but never giving a false positive, which would indicate a 100% chance to have the Kung Flu. Without specifically the rates for a false positive we can't say with certainty.
Turns out giving a test with a binary outcome a flat accuracy is nebulous.

Shit, that didn't even cross my mind. Good thinking.

hurrr D

It absolutely does, you mongoloid.

The test is 95% accurate. .1% of the population is infected. This means that 5% of 99.9% of the population does not have it but tests positive. So 5% of the population tests positive while they don't have it.

If you get tested positive, you have a 5% probability of having it. Maths is hard.

This. Precision and recall are two different measurements that are important here.

100%, got some sitting in the fridge

Distorting the question. This is a simple probability question, so stop invoking cosmic rays and whatnot.

The question asks for the chance of getting corona. This isnt specified.
The chance of the test coming out as negative and being wrong is 2%

>Makes up a stupid question

95%, with a +/- 5% variance for accuracy

How do you know that 5% margin of error is for false positives instead of false negatives?

Jesus how dumb are you fucks

If someone told you they have 100% accuracy, does that mean they are wrong 100% of the times?

>I don't get maths so I'll call you all stupid instead.

0%. The virus is a hoax I've been taking my kids to Walmart everyday let them play with all the toys for a couple hours to run off energy. No ones there. We're all gonna be fine

Fair enough.

OP here.
Only 1 person so far as gotten it right, you guys are a disgrace, let me explain.

out of 1000 people, only 1 has corona, but 50 will test positive.
You are 1 of those 50 people and only 1 of those 50 has corona.
1/50 = 2%

If you had any kind of confidence in your answer, you need to rethink some things.

It is called statistical hypothesis testing. Look it up

B is the most correct with the information provided, but depending on whether the 5% inaccuracies is false negatives or false positives, A may be the correct answer.

B
