Please complete the following assignment.1. Describe the difference between repairable and
non-repairable items. What kind of effect might this difference have on
reliability? List examples of repairable and non-repairable items in our
everyday life. (10 points)2. Explain the difference between reliability and durability
and how they can be specified in a product development program. (10 points)3. A space vehicle requires five out of its six main engines
to operate in order to achieve orbit. If each engine has a reliability of 0.98
determine the reliability of achieving orbit. (20 points)4. What is the probability of having not more than 20 but
not less than 10 failures if n=100 p=0.14 for a binomial distribution? (20 points)5. What is the probability of having not more than 20 but
not less than 10 failures if n=100 p=0.14 for a normal distribution (mean=np
variance=npq)? (20 points)
6. In the question 3 we
assume the six engines are independent. Please describe three factors that
could invalidate this assumption. And how will it affect the results you have
in question 3 if the independent assumption is invalid? (20
