Question

rt AA field party is capable of making taping observations with a standard deviation of ± 0.04 ft per 100 ft tape length. What standard deviation would be expected in a distance 200 ft taped by this party?Express your answer to three significant figures and include appropriate units.

Answer 1

Answer:

±0.0283 ft

Step-by-step explanation:

Sometimes

$E = \frac{E_{series} }{\sqrt{n} } \\E_{series} = E\sqrt{n} \\E_{series} =0.04 * \sqrt{\frac{200}{100} }$

E_{series} =  ±0.0283 ft
