If the claims are true, the probability that a dementia patient is tested negative for dementia is 0.60. rer There is insufficient information to calculate the negative predictive value for tumour diagnosis with their claim.

diseases are independent. Which of the following is correct about the tool?
If the claims are true, then Sensitivitytumour = 0.60.
If the claims are true, the probability that a dementia patient is tested negative for
dementia is 0.60.
Correct Answer
There is insufficient information to calculate the negative predictive value for tumour
diagnosis with their claim.
