Question

In 'Stat' World it is known that 10% of the entire population of 100 million people are infected with 'HALO' disease. 'HALO' has a range of outcomes that range from 'asthma' to 'reduced life span' to 'imminent death'.

'Stat World' has developed a screening to test for the 'HALO', and this test has an accuracy of 80% in identifying 'HALO'.

'Stat World' has also developed a 'HALO' treatment ('BLOCK') that has 90% rate of full cure if you have 'HALO'. However if you receive 'BLOCK' treatment and do not have 'HALO' disease you will be incurably infected with 'HALO'.

 

  • What is the probability that you have 'HALO' if you test positive for 'HALO'?

 

  • What is the probability that you have 'HALO' if you test negative for 'HALO'?

 

  • What is the probability that you are harmed by 'BLOCK' treatment if you tested positive for 'HALO'?

 

  • What is percentage of population that will be cured by 'BLOCK' if all positive 'HALO test results are treated with 'BLOCK'?

 

      (e) What is percentage of population that will be harmed by 'BLOCK' if all positive 'HALO test results are treated with 'BLOCK'?
