Chase had a 6.3% error

Step-by-step explanation:

Percent Error

If the real measure of a certain magnitude is M and the experimental measure is N, then the error is N-M.

To express that difference as a percentage, we divide by the real measure:

The actual length of the line is M=9.5 inches, but Chase measured N=8.9 inches, thus the percent error is:

pct = -6.316%

To the nearest tenth:

pct = -6.3%

Chase had a 6.3% error
