9) Two professors at a nearby university want to coauthor a new textbook in either
economics or statistics. They feel that if they write an economics book, they have a 50
percent chance of placing it with a major publisher, and it should ultimately sell about
40,000 copies. If they cannot get a major publisher to take it, then they feel they have
an 80 percent chance of placing it with a smaller publisher, with ultimate sales of
30,000 copies. On the other hand, if they write a statistics book, they feel they have a 40
percent chance of placing it with a major publisher, and it should result in ultimate sales
of about 50,000 copies. If they cannot get a major publisher to take it, they feel they
have a 50 percent chance of placing it with a smaller publisher, with ultimate sales of
35,000 copies.

13) The head of operations for a movie studio wants to determine which of two new
scripts they should select for their next major production. (Due to budgeting constraints,
only one new picture can be undertaken at this time.) She feels that script 1 has a 70
percent chance of earning about $10,000,000 over the long run, but a 30 percent chance
of losing $2,000,000. If this movie is successful, then a sequel could also be produced,
with an 80 percent chance of earning $5,000,000, but a 20 percent chance of losing
$1,000,000. On the other hand, she feels that script 2 has a 60 percent chance of earning
$12,000,000, but a 40 percent chance of losing $3,000,000. If successful, its sequel
would have a 50 percent chance of earning $8,000,000, but a 50 percent chance of
losing $4,000,000. Of course, in either case, if the original movie were a flop, then no
sequel would be produced.
What is the expected value of selecting script 2?
A.$15,000,000
B.$9,060,000
C.$8,400,000
D.$7,200,000
E.$6,000,000
14) An electronics firm produces two models of pocket calculators: the A-100 (A),
which is an inexpensive four-function calculator, and the B-200 (B), which also features
square root and percent functions. Each model uses one (the same) circuit board, of
which there are only 2,500 available for this week’s production. Also, the company has
allocated a maximum of 800 hours of assembly time this week for producing these
calculators, of which the A-100 requires 15 minutes (.25 hours) each, and the B-200
requires 30 minutes (.5 hours) each to produce. The firm forecasts that it could sell a
maximum of 4,000 A-100s this week and a maximum of 1,000 B-200s. Profits for the
A-100 are $1.00 each, and profits for the B-200 are $4.00 each. What is the objective
function?
A.$4.00A + $1.00B = Z
B.$0.25A + $1.00B = Z
C.$1.00A + $4.00B = Z
D.$1.00A + $1.00B = Z
E.$0.25A + $0.50B = Z
15) Which is not an area of significant difference between manufacturing and service
operations?

following results:
What is the sample proportion of failures (p) for Prof. D?
A.0
