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 3.2 percent chance that the flight will be diverted for an immediate landing. Suppose the response center is called 8,429 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 approximate normal probability of at least 261 diversions?(
Round your standard deviation value to 4 decimal places and yourz-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 approximate normal probability of fewer than 313 diversions?(
Round your standard deviation value to 4 decimal places and yourz-value to 2 decimal places. Use Appendix C-2 to find probabilities. Round your final answer to 4 decimal places.)


Probability        ______________
