Question

Rather than use the two scoops of coffee recommended by the manufacturer, a coffee aficionado uses three scoops of coffee per pot. What is the relative error?​

Answer 1

Answer: Relative error = 50%

Step-by-step explanation:

Relative error Re = Absolute error/True value × 100%

True value = 2 scoops

Measured(used) value = 3 scoops

Absolute error Ae = measured(used) value - True value

= 3 scoops - 2 scoops

Ae = 1 scoop

Re = 1/2 × 100%

Re = 50%
