A new test is developed to test for organic matter in soil samples, giving "positive" or "negative" results to indicate that a sample does or does not
contain organic matter.
For a soil sample that contains organic matter, the test will give a positive result 95% of the time and a negative result(false negative) 5% of the time.
For a soil sample that does not contain organic matter, the test will give a positive result (false positive) 20% of the time and a negative result 80% of
the time
A study included a population of 1,000 soil samples, and 70% of those studied where known to contain organic matter.
Fill in the missing values in the table and statement below. If necessary, round the percentage to one decimal place.
