approximately what percentage of the adult population was obese that year?
%
(b) during which year was the percentage the lowest?
approximately what percentage of the adult population was obese that year? (round your answer to the nearest percent.)
%

Explanation:

Step1: Analyze the graph for the highest point

Look at the y - values (percentage) for each year. The highest y - value corresponds to the highest percentage.

Step2: Identify the year and percentage for the highest point

From the graph, the highest point (y - value) occurs at a certain year. The y - axis is labeled "Percentage". Reading the graph, the highest y - value is approximately 40 (for the year 2014).

Step3: Analyze the graph for the lowest point

Look at the y - values (percentage) for each year. The lowest y - value corresponds to the lowest percentage.

Step4: Identify the year and percentage for the lowest point

From the graph, the lowest y - value occurs at a certain year. The lowest y - value is approximately 30 (for the year corresponding to the start of the graph, assume it's 2004 as per the x - axis scale near the first point).

Answer:

(a) Year: 2014, Percentage: 40%
(b) Year: 2004, Percentage: 30%
