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.

Answer

To find the upper class boundary for the second class, follow these steps: 1. Identify the second class: Looking at the table, the second class interval is 22-32. 2. Identify the upper limit of the second class: The upper limit is 32. 3. Identify the lower limit of the next (third) class: The lower limit of the third class is 33. 4. Calculate the boundary: Class boundaries are halfway between the upper limit of one class and the lower limit of the subsequent class to eliminate gaps between data intervals. Therefore, calculate the average: (Upper limit of second class + Lower limit of third class) / 2 = (32 + 33) / 2 = 65 / 2 = 32.5. The upper class boundary for the second class is 32.5.
