Question

Fan + Medal

Answer 1

The board of directors of a company knows that the probability that the carbon emission from the company’s manufacturing unit is exceeding the permissible level is 35%. A consultant is hired to use a carbon footprint calculator to test for the emission level. The accuracy of this test is said to be 85%.

Answer 2

What is the probability that the carbon emission from the manufacturing unit is within the permissible level, and the test predicts the same outcome?

Answer 3

0.2975



0.0525



0.0975



0.5525



0.6325

Answer 5

this problem is rather poorly stated because it does not define what they mean by 'accuracy'. if we take it to mean that, if emissions are excessive, there is an 85% the test will say so, and if emissions are not, the test will correctly indicate that with probability 85%/

Answer 6

there is enough information if we make this assumption, but the answer will surprise you. I won't give it to you, but i will try to get you going on how to find it.
let
P(excessive levels of emissions)=P(A)=0.35
P(testing positive)=P(B)
we are given with the accuracy statement that
P(B|A)=0.85
P(BC|AC)=0.85

Answer 7

do you know baye's rule?

Answer 8

No I don't

Answer 9

how about the total probability theorem? do you know that?

Answer 10

Just assume I know nothing geometry is tough for me

Answer 11

ah

Answer 12

This does not seem like geometry though, probability is in algebre 2 I think?

Answer 13

Well it's from my geomtry class

Answer 14

All the ways I would do it seems like you havent learned yet, sorry I couldnt be much help :/

Answer 15

You can't walk me through, step by step?

Answer 16

Heyy
