### Stress at Work: Probability AssessmentIn a poll about work, 82% of respondents said that their jobs were sometimes or always stressful. Ten workers are chosen at random. Round the answers to four decimal places.#### Part 1 of 4:**(a) What is the probability that exactly 9 of them find their jobs stressful?**The probability that exactly 9 of them find their jobs stressful is \( 0.3200 \).#### Part 2 of 4:**(b) What is the probability that more than 6 find their jobs stressful?**The probability that more than 6 find their jobs stressful is \( 0.5400 \).#### Part 3 of 4:**(c) What is the probability that fewer than 5 find their jobs stressful?**The probability that fewer than 5 find their jobs stressful is \( 0.2600 \).#### Part 4 of 4:**(d) Using a cutoff of 0.05, would it be unusual if fewer than 4 of them find their jobs stressful?**It **would** be unusual if fewer than 4 of them find their jobs stressful, since the probability is \( \boxed{} \).
