Refer to Data Set 20 in Appendix B. If annual person-days lost due to work stoppages from 1976 to 1999 are analyzed, for six groups of transportation industries, the median annual number of person-days lost overall is 10,595. Find the median number of person-days lost due to work stoppages in just the truck-based transportation industry for 1976 to 1999. Test at the 0.05 level of significance, and assume that the data in Data Set 20 are representative of all years. Test the claim that the median number of person-days lost in the truck-based group is smaller than the median of 10,595 for all transportation groups combined.
