    Answer:

    false negatives – 2%

    false positives – 3%

    Step-by-step explanation:

    Here is the complete question :

    A test to detect an infection gives a positive result 98% of the time when an infection is present. It is 97% accurate when an infection is not present.

    % of results will be false negatives, and % of results will be false positives.

    False negative means a negative result which in actuality it is positive

    False negative = 100% – percent of positive result

    100% – 98% = 2%

    False positive result means a positive result which in actuality is negative

    False positive = 100% – percent of false positive

    100 – 97 = 3%
