a. Develop a spreadsheet from which one may obtain a graph such as Figure 12–17 for sequential sampling. Store the values of p0, p1, , and  in cell locations so that these can be altered at will. Print a graph for p0  .05, p1  .20,   .05, and  

.10. Allow for n  100.

b. Sequential sampling resulted in the following: the first 40 items were good, item 41 was defective, item 68 was defective, and items 86 and 87 were defective. Place these results on the graph you obtained in part (a). Is the lot accepted, rejected, or neither on or before testing the 87th item?
