A data set has values ranging from a low of 10 to a high of 50. The class width is to be 10. What's wrong with using the class limits 10-20, 21-31, 32-42, 43-53 for a frequency table with a class width of 10? Each data value must fall into one class. Some data values do not have a class. The classes overlap so that some data values fall within two classes. The classes listed have a class width of...

Construct a grouped frequency distribution table (GFDT) for this data set. You want 10 classes with a "nice" class width. Your classes should be labeled using interval notation. Each class contains its lower class limit, and the lower class limits should all be multiples of the class width. In that the data appears to be discrete, use a closed-interval to label each class. 594 940 614 543 619 606 931 674 802 618 807 486 633 745 486 873 773...
