Question

this line plot shows data about trails in a state park. what is true about the data in this line - plot? length of trails (in kilometers) four trails are 3 kilometers long. the longest trail is exactly 3 kilometers long. more than half the trails are 4 1/2 kilometers or shorter. half the trails are 4 1/2 kilometers or longer.

Explanation:

Step1: Count total number of data - points

Count all the dots on the line - plot. There are 20 dots in total.

Step2: Count number of trails 4.5 kilometers or shorter

Count the dots for lengths 2.5, 3, 3.5, 4, and 4.5 kilometers. There are 12 dots for these lengths.

Step3: Analyze the proportion

Since 12 > 10 (half of 20), more than half the trails are 4.5 kilometers or shorter.

Answer:

More than half the trails are 4.5 kilometers or shorter.
