question archive Supplementary Problem 544 A survey conducted for the Northwestern National Life Insurance Company revealed that 70% of American workers say job stress caused frequent health problems One in three said they expected to burn out in the job in the near future Thirty-four percent said they thought seriously about quitting their job last year because of workplace stress Fifty-three percent said they were required to work more than 40 hours a week very often or somewhat often Appendix A Statistical Tables a Suppose a random sample of 10 American workers is selected What is the probability that more than seven of them say job stress caused frequent health problems? (Round to 3 decimal places)What is the expected number of workers who say job stress caused frequent health problems?
