Explanation / Answer
Mortality rate because of the disease can be found out of 100,000 by dividing number of deaths due to the condition by total population and then multiply by 100,000
(939500×100000)÷299,000,000.
That comes out to be 314.21
So the mortality rate bcoz of the condition out of 100,000
Is 314.21
For the second one if we assume only women took the test, for finding the ones with wrong result we have to add both false positive and false negatives - 1454+19 that comes out to be 1473
