Question

Jason predicted that 277 students would attend the school dance. The actual number was 250. What is the precent error of Jason's prediction?

Answer 1

9.7%

Explanation:

Given data

Expected value= 277

Actual value= 250

%Error= Actual- Expected/Expected *100

%Error= 250-277/277 *100

%Error= 27/277 *100

%Error= 0.097*100

%Error= 9.7

Hence the error is 9.7%
