Medical labs rely on blood-analyzing machines to measure
the numbers and types of blood cells in blood samples. A
machine ran three tests to measure the number of red
blood cells in one sample. The results are shown in the
table.
Test 1
Test 2
Test 3
4.251 million cells/microliter
4.250 million cells/microliter
4.249 million cells/microliter
The actual red blood cell count of the sample was 4.25 million
cells/microliter. Which statement best describes the accuracy and precision
of the measurements?
