When confronted with an in-flight medical emergency, pilots and crew can consult staff physicians at a global response center located in Arizona. If the global response center is called, there is a 4.7 percent chance that the flight will be diverted for an immediate landing. Suppose the response center is called 8,475 times in a given year.
(a) What is the expected number of diversions? (Round your answer to 2 decimal places.)
Expected number?
(b) What is the probability of at least 391 diversions? (Round your standard deviation value to 4 decimal places and your z-value to 2 decimal places. Use Appendix C-2 to find probabilities. Round your final answer to 4 decimal places.)
Probability ?
(c) What is the probability of fewer than 450 diversions? (Round your standard deviation value to 4 decimal places and your z-value to 2 decimal places. Use Appendix C-2 to find probabilities. Round your final answer to 4 decimal places.)
