S = -15

-S = -(-15) = 15

Answer:

The percentage error in the prediction = 10.20%

Step-by-step explanation:

A sports broadcaster predicts a basketball team will score 88 point me in the next game.

If the team has actually scored 98 points we have to find the percentage error in the broadcaster's prediction.

The deviation of the prediction from the actual value = 98 - 88 = 10.

The formula for finding error percentage = $\frac{deviation from actual value}{prediction}$

= $\frac{10}{98} \times 100$

= 10.20 %

The percentage error = 10.20%
