2.Analysis of Last Digits The accompanying table lists the last or rightmost digits of weights of the females listed in Data Set 1 “Body Data” in Appendix B. The last digits of a data set can sometimes be used to determine whether the data have been measured or simply reported. The presence of disproportionately more 0s and 5s is often a sure sign that the data have been reported instead of measured.

a. Using the table, find the mean and standard deviation of those last digits. Are the results statistics or parameters?

b. Examine the given table to determine if there is anything about the sample data (such as disproportionately more 0s and 5s) suggesting that the given last digits are not random? Or do they appear to be random?

c. Does the table describe a probability distribution? Why or why not?
