An electronics manufacturer finds that 98% of the processors they produce are acceptable. The quality control department will test the next batch of 10000 processors.

What is the approximate probability that the number of unacceptable processors in this batch is

between 190 and 220? Use the standard normal distribution to approximate this probability,

and justify your use of this approximation.

The probability that a current generation iPhone has a particular flaw is 0.07. A quality control group randomly selects 900 iPhones and checks them for this flaw. Use the Normal Approximation to the Binomial Distribution to estimate the probability that the number of iPhones with the flaw in the sample is at most 59. Round your z-score to 2 decimal places. Round your answer to 3 decimal places. Do not forget the .5 continuity correction. Hint: The mean is 63...
