Question

A technician ran several blood tests this morning. She completed 13 tests during the first

hour, 19 tests during the second hour, 14 tests during the third hour, and 16 tests during
the fourth hour.
a. What is the average number of tests the technician completed in 1 hour? Round to
the nearest whole number.
b. If the technician works three hours this afternoon, about how many tests will she complete?

Answer 1

a. about 16 tests b. about 48 tests

Explanation:

To find the average, add the numbers and then divide the sum by the number of terms: 13+19+14+16=62, and there are 4 addends, so 62/4, which is 15.5. 15.5 to the nearest whole number is 16.

16 per hour, and she works 3 hours, so 3x16, which is 48.
