Consider the following frequency table representing the distribution of hours students spend on homework in a week. Determine the upper class boundary for the second class. Table Data: - Class 20-26, Frequency 3 - Class 27-33, Frequency 8 - Class 34-40, Frequency 6 - Class 41-47, Frequency 6 - Class 48-54, Frequency 4

Answer

To find the upper class boundary for the second class, follow these steps: 1. Identify the second class in the frequency table, which is 27-33. The upper class limit for this class is 33. 2. Identify the lower class limit of the next class (the third class), which is 34. 3. Calculate the gap between these two classes by subtracting the upper limit of the second class from the lower limit of the third class: 34 - 33 = 1. 4. The class boundary is the midpoint of this gap. Divide the gap by 2: 1 / 2 = 0.5. 5. Add this value to the upper limit of the second class to find the upper class boundary: 33 + 0.5 = 33.5. Therefore, the upper class boundary for the second class is 33.5.
