When purchasing bulk orders of batteries , a toy manufacturer uses
this acceptance sampling plan; Randomly select and test 49
batteries and determine whether each is within specifications. The
entire shipment is accepted if at most 2 batteries do not meet
specifications. A shipment contains 7000 batteries, and 2% of them
do not meet soecifications. what is the probability that this whole
shipment will be accepted? will almost all such shipments be
accepted? or how many will be rejected?
