Question

answer the questions about the dot plot below.
the set of data below represents the time, in seconds, that it takes different students to run 100 meters.
● = 1 student
dot plot with time (sec) on x - axis: 13.0, 13.1, 13.2, 13.3, 13.4, 13.5, 13.6, 13.7, 13.8, 13.9; dots above: 13.0 (1), 13.1 (1), 13.2 (1), 13.4 (2), 13.5 (2), 13.6 (3), 13.9 (1)
what is the time of the fastest student? sec
what is the time of the slowest student? sec
what is the range of the set of data? sec

Explanation:

Step1: Find the fastest student's time

The fastest student takes the least time. From the dot plot, the leftmost dot is at 13.0 seconds.

Step2: Find the slowest student's time

The slowest student takes the most time. From the dot plot, the rightmost dot is at 13.9 seconds.

Step3: Calculate the range

Range is the difference between the maximum and minimum values. So, \( 13.9 - 13.0 = 0.9 \) seconds.

Answer:

Fastest student's time: \( 13.0 \) sec
Slowest student's time: \( 13.9 \) sec
Range of the data: \( 0.9 \) sec
