Question: Analysis of Last Digits Analysis of the last digits of sample data values sometimes reveals whether the data have been accurately measured and reported. When single digits 0 through 9 are randomly selected with replacement, the mean should be 4.5 and the standard deviation should be 2.87. Reported data (such as weights or heights) are often rounded so that the last digits include disproportionately more 0’s and 5’s. Use the last digits in the reported lengths (in feet) of the 73 home runs hit by Barry Bonds in 2001 to test the claim that they come from a population with a mean of 4.50. Use a 0.05 significance level. The 73 home-run distances (listed in Data Set 17 Appendix B) have last digits with a mean of 1.753. Based on the results, does it appear that the distances were accurately measured?
