ENGRD 2700 Problem Set 2 By the end of the July 7 th lecture you should have Read and digested the material up to section 4.4. Figured out how to use JMP to compute binomial, geometric, Poisson and normal probabilities. Problems: x/y=page x, problem y; Use JMP where possible. 1. 81/82 2. 83/104 3. 99/24 4. 107/32 5. 107/36 6. 113/48 7. 115/66 8. 121/74 9. 126/92 10. 135/6 11. 144/22 12. 155/36 13. Critical key-entry errors in the data processing operation of a large district bank occur 0.1% of the time. If a random sample of 10,000 entries is examined, answer the following questions: a. What probability model is appropriate? What is the expected number of errors i.e. , and their standard deviation ? Round the standard deviation to two significant digits.

Unformatted text preview: b. What is the probability of observing fewer than eighteen errors using a binomial probability model? Use JMP to answer this question and round the probability to 5 significant digits.: c. What is the probability of observing fewer than eighteen errors using a Poisson probability model? Use JMP to answer this question and round the probability to 5 significant digits. d. What is the probability of observing fewer than eighteen errors using a normal probability model (without a correction for continuity)? Use JMP to answer this question and round the probability to 5 significant digits. e. Which of the Poisson and the normal probability models gives a better approximation to the binomial probability model in (b)?...
