In a wood cutting process to produce rulers, the mean of rulers height is set to be

equal 100 cm at all times. If the mean height of rulers is not equal to 100 cm, the

process will stop immediately. The height for a sample of 10 rulers produced by

the process were shown below:

100.13

100.11 100.02

99.99

99.98

100.14

100.03

100.10 99.97

100.21

Based on the sample, can we stop the wood cutting process at = 0.01?
