Question

initial class boundary of 60.5 and a class width of 5.

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the initial class boundary, we need to subtract half of the class width from the lower class limit and add half of the class width to the upper class limit.

Lower class limit = 60.5
Class width = 5

Initial class boundary = Lower class limit - (0.5 * Class width) = 60.5 - (0.5 * 5) = 60.5 - 2.5 = 58

Therefore, the initial class boundary is 58.

To find the class boundaries for a given initial class boundary and class width, follow these steps:

1. Identify the initial class boundary: In this case, the initial class boundary is 60.5.

2. Determine the class width: In this case, the class width is 5.

3. Calculate the lower class boundaries: Subtract the class width from the initial class boundary to get the lower class boundaries. For example, the lower class boundary for the first class interval is 60.5 - 5 = 55.5.

4. Calculate the upper class boundaries: Add the class width to the initial class boundary to get the upper class boundaries. For example, the upper class boundary for the first class interval is 60.5 + 5 = 65.5.

Repeat steps 3 and 4 until you have obtained the desired number of class intervals.

So, the class boundaries for the given initial class boundary of 60.5 and a class width of 5 would be:

55.5 - 60.5 - 65.5 - ...
