Question

If sabrina’s time were 13.26 seconds instead of 13.25 seconds would that change your estimate for the total time? Explain.

Answer 1

the answer is no because the time intervals are not capable of meeting

Answer 2

It would change my estimation because the error is greater than tolerance

Explanation:

• Tol. for exact time (13.26);

`{ \sf{ = 0.5 * 10 {}^( - 2) }} \\ = { \sf{0.005}}`

Therefore, error;

`{ \sf{error = 13.26 - 0.005 = 13.255 \: s}}`

• Tol for expected time (13.25);

Tol is the same, = 0.005

`{ \sf{error = 13.25 - 0.005 = 13.245 \: s}}`

• Percentage error;

`{ \sf{overall \: error = 13.255 - 13.245}} \\ = { \sf{0.01}}`

0.005 < tol < 0.01
