Answer:
10.2%
Step-by-step explanation:
Prediction of the broadcaster = 88 points
Actual score scored = 98points
% error = actual score-predicted score/actual score × 100℅
Substitute the given scores into the formula;
%error = 98-88/98 × 100
%error = 10/98 × 100
%error = 1000/98
%error = 10.2%
Hence the broadcaster percentage error is approximately 10.2%
