Question

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

Answer 1

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.
