Question

a study was conducted on three types of home siding and the type of damage done to the siding by woodpeckers. each hole made by a woodpecker was classified as either drumming (territorial signaling), foresting (looking for food), or nesting. the following bar chart shows the relative frequency of the holes for each type of siding. which of the following statements is supported by the bar chart? a the proportion of holes created for drumming is the same for all three siding types. b the proportion of holes created for drumming is greatest for grooved plywood.

Explanation:

Step1: Observe the bar - chart

We look at the height of the light - colored (drumming) segments for each type of siding: Clapboard, Grooved Plywood, and Nonwood.

Step2: Analyze Option A

For Clapboard, Grooved Plywood, and Nonwood, the proportion of drumming holes is different. So, option A is incorrect.

Step3: Analyze Option B

By visually inspecting the bar - chart, the height of the drumming segment for Grooved Plywood is the tallest among the three types of siding. So, the proportion of holes created for drumming is greatest for grooved plywood.

Answer:

B. The proportion of holes created for drumming is greatest for grooved plywood.
