Question

estimating precision
use the table to answer the questions.
what is the fastest time trial for the first quarter checkpoint? seconds
what is the slowest time trial for the first quarter checkpoint? seconds
what is the range of times measured for this checkpoint? seconds
time of trial#1 (s) 2.15
time of trial#2 (s) 2.05
time of trial#3 (s) 2.02
average time (s) 2.07

Explanation:

Fastest Time Trial

Step1: Identify trial times

Trial times: 2.15, 2.05, 2.02.

Step2: Find minimum value

The smallest time is 2.02.

Step1: Identify trial times

Trial times: 2.15, 2.05, 2.02.

Step2: Find maximum value

The largest time is 2.15.

Step1: Recall range formula

Range = Maximum - Minimum.

Step2: Substitute values

Maximum = 2.15, Minimum = 2.02. So, \( 2.15 - 2.02 = 0.13 \).

Answer:

2.02

Slowest Time Trial
