acceptable voltages

67.   Suppose that 90% of all batteries from a certain supplier have acceptable voltages. A certain type of ashlight requires two type-D batteries, and the ashlight will work only if both its batteries have ac- ceptable voltages. Among ten randomly selected ashlights, what is the probability that at least nine will work? What assumptions did you make in the course of answering the question posed?

 

68.   A very large batch of components has arrived at a distributor. The batch can be characterized as ac- ceptable only if the proportion of defective compo- nents is at most .10. The distributor decides to ran- domly select 10 components and to accept the batch only if the number of defective components in the sample is at most 2.

 

a.   What is the probability that the batch will be ac- cepted when the actual proportion of defectives is .01? .05? .10? .20? .25?

 

b.   Let p denote the actual proportion of defectives in the batch. A graph of P(batch is accepted) as a function of p, with p on the horizontal axis and P(batch is accepted) on the vertical axis, is called the operating characteristic curve for the accep- tance sampling plan. Use the results of part (a) to sketch this curve for 0 p 1.

 

c.    Repeat parts (a) and (b) with 1 replacing 2  in the acceptance sampling plan.

 

d.   Repeat parts (a) and (b) with 15 replacing  10 in the acceptance sampling plan.

 

e.    Which of the three sampling plans, that of part (a), (c), or (d), appears most satisfactory, and why?
