Explanation:

Part a

Step1: Find the longest pencil

Look at the line plot. The rightmost 'x' is at 11 cm, so the longest pencil is 11 cm.

Step2: Find the shortest pencil

Look at the line plot. The leftmost 'x' is at 5 cm, so the shortest pencil is 5 cm.

Step1: Identify the most common length

Count the number of 'x's at each length. The length with the most 'x's is 7 cm (by visually inspecting the line plot, the column at 7 has the highest number of marks).

Answer:

Longest: 11 centimeters, Shortest: 5 centimeters
