A call center recruites operators on a 2 week probationary period before hiring a select group as permanent employees. The average time spent per callby the operators is known to follow a normal distribution with a mean of 35 minutes and a standard deviation of 9 minutes. Operators with average calldurations between 29 minutes and 51 minutes during the probationary period get hired in permanent positions; and the rest are fired.a. What is the probability that a randomly selected operator will get fired after the probationary period?Answer in exact fraction, or rounded to at least 4 decimal places.b. Determine the 74 percentile value for the call durationAnswer in exact fraction, or rounded to at least 2 decimal places.minutesc. The operators who place within the top 8.46% of the accepted call duration range are awarded a special bonus package. So, what is the minimumaverage call duration you should try to achieve if you want to receive the bonus package?Answer in exact fraction, or rounded to at least 2 decimal places.minutes
