A manufacturer of flashcubes wants to estimate the probability that a flashcube will work. Since, destructive testing is involved; he wants to keep the sample size as small as possible. Find the number of observations that must be taken to estimate the probability within 0.04 and with 95% confidence of that if a. He has no idea of the percent defective. b. He believes that the percent defective is no more than 6%.
