4 The Bullington Company wants a time standard established on the painting operation of souvenir horseshoes for the local Pioneer Village. Work sampling is to be used. It is estimated that work- ing time averages 95 percent of total time (working time plus idle time). Aco-op student is avail- able to do the work sampling between 8:00 A.M. and 12:00 noon. Sixty working days are to be used for the study. Use Exhibit TN5.11 and an absolute error of 2.5 percent. Use the table of ran- dom numbers (Appendix B) to calculate the sampling schedule for the first day (that is, show the times of day that an observation of working/idle should be made). Hint: Start random number selection with the first tour.
