Here is a data set: 362 479 205 287 144 329 427 432 431 332 327 285 324 232 282 144 200 368 408 253 198 358 467 312 222 480 354 587 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. This problem is to determine what the class width and the first lower class limit should be. What is the best class width for this data set? optimal class width = What should be the first lower class limit? 1st lower class limit =The following data represents the age of 30 lottery winners. 20 25 27 27 28 28 35 41 43 44 44 46 49 54 54 56 58 59 59 60 60 61 62 64 65 67 68 70 72 81 Complete the frequency distribution for the data.
