Transcript text: The histogram to the right represents the weights (in pounds) of members of a certain high-school debate team. What is the class width? What are the approximate lower and upper class limits of the first class? What is the class width? The class width is $\square$ (Simplify your answer)

Solution

Solution Steps

Step 1: Identify the class width

The class width is the difference between the lower limit of one class and the lower limit of the next class. From the histogram, the classes appear to be 110-120, 120-130, etc.

Step 2: Calculate the class width

Subtract the lower limit of the first class from the lower limit of the second class: \[ 120 - 110 = 10 \]

Step 3: Determine the lower and upper class limits of the first class

The first class starts at 110 and ends at 120.
