Here is a data set: S? 3'95 354 313 35.5. 351 m - - 354 34s The goal is to construct a grouped frequency distribution table lGFDTi for this data set. The GFDT should have 11} 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. This problem is to determine what the class Iwidth and the rst lower class limit should be. 'n'-'hat is the best class width for this data set'.' optimal class width =| I 1st lower class lirnit =i
