Answer 1

Answer:

the correct answer is 0.11s

Answer 2

Answer:

(b) 0.11 seconds.

Explanation:

First of all, we will calculate the absolute value.

So,

2.63 + 2.56 + 2.42 + 2.71 + 2.80 / 5

                 

T 1   = 2.63 - 2.62 = 0.01

T 2  = 2.62 − 2.56 = 0.06

T 3  = 2.62 − 2.42 = 0.20

T 4  = 2.71 − 2.62 = 0.09

T 5  = 2.80 − 2.62 = 0.18

Now we are in a position of finding the absolute error.

T =   T 1  +  T 2 +  T 3 +  T 4  +   T 5   / 5

= 0.01 + 0.06 + 0.20 + 0.09 + 0.18 / 5

= 0.54 / 5

= 0.11 s

∴ The average absolute error is 0.11 s.

Hope helps!
