2. (2.5pt) Exercise 3.29 (3.33) page 101 (105), but replace .125 with .0125
in f (x). Be sure to identify the distribution of the time to failure and
any associated parameter values for the time to failure.
3. (1pt) Exercise 3.31 (3.35) page 101 (105). “Evaluate the performance of
this decision rule” means finding the probability the process is stopped
after inspecting a sample. Also identify the distribution and any associated parameter values for the number of nonconforming units in a
sample of 25 units.

5. (2pt) Exercise 3.35 (3.43) page 101 (106). Only do parts (a) and (d).
In (a) be sure to identify the distribution and any associated parameter
values for the number of nonconforming components in a sample of 5
components.
6. (2pt) Exercise 3.42 (3.50) page 102 (107). The first question should be
interpreted as “what is the probability the inspector will have to walk
exactly 5000 feet?”.
7. (1pt) Exercise 3.44 (3.52) page 102 (107).
8. (1pt) Exercise 3.48 (3.56) page 102 (107).
