Births Use the birth weights (grams) of the 400 babies listed in Data Set 3 “Births” in Appendix B. Examine the list of birth weights to make an observation about those numbers.

How does that observation affect the way that the results should be rounded?

25. In Exercises 25 and 26, find the mean of the data summarized in the frequency distribution.
Also, compare the computed means to the actual means obtained by using the original list of data values, which are as follows: (Exercise 25) 224.3; (Exercise 26) 255.1.
