Answer

Explanation:

Step1: Understand margin - of - error for ruler measurement

When measuring with a ruler marked in centimeters, the margin of error is half of the smallest unit of measurement. The smallest unit here is 0.1 cm, so the margin of error is 0.05 cm.

Step2: Calculate the range

To find the range of values within the margin of error, we subtract and add 0.05 cm from the measured value of 1.9 cm. So the lower - bound is (1.9 - 0.05=1.85) cm and the upper - bound is (1.9 + 0.05 = 1.95) cm.

Answer:

1.85 cm to 1.95 cm
