Answer:

E = 12

RE = 0.4

Step-by-step explanation:

The estimation error (E) is defined as the absolute value of the difference between the actual value (RV) and the estimated value (EV). With RV = 30 and EV = 42.

E = | EV - RV | = | 42 - 32 | = | 12 | = 12

A complementary concept could be the relative error (RE), which is defined as the ratio between the absolute error and the actual value.

RE = E / RV = 12/30 = 2/5 = 0.4
