Question

Here is a data set: 27300 29700 25900 28900 31300 28600 31400 31200 31700 29200 34600 25100 30700 30800 29400 29900 30400 28800 30200 31700 32500 29300 27200 27200 30100 28500 31100 29600 The goal is to construct a grouped frequency distribution table (GFDT) for this data set. The GFDT should have 10 classes with a "nice" class width. Each class should contain its lower class limit, and the lower class limits should all be multiples of the class width. It has been determined that the ideal class width would be 1000. This problem is to determine what the first lower class limit should be. What is the minimum of this data set? min = What is the minimum divided by the class width? minimum ÷ class width = This number rounds down to what integer? Using this value, if the goal is to have a lower class limits that are multiples of the class width, what should be the first lower class limit? 1st lower class limit =
