Question

What is the amount of error in Lamont's estimate is

Answer 1

The percentage of error is given by:

$Error=\frac{|Measured-Real|}{Real}\times100$

Where:

Measured = 160

Real = 159

so:

$Error=\frac{|160-159|}{159}\times100=\frac{1}{159}\times100\approx0.6$

Answer:

0.6%

8a.

Amount of error = Measured - real = 160 - 159 = 1
