Answer:
The most likely length of the line is 69.4012 meters.
The calculated standard deviation amounts to 0.0032 meters.
Step-by-step explanation:
In the problem, the following values are provided:
69.401, 69.400, 69.402, 69.396, 69.406, 69.401, 69.396, 69.401, 69.405, 69.404
Formula:
where
represent data points,
is the average, and n indicates the count of observations.


The most likely length of the line is 69.4012 meters.
Sum of squares of differences = 0.0001016

The calculated standard deviation amounts to 0.0032 meters.
