Which is the best statement regarding an operating characteristic curve? A. As the fraction defective increases, the probability of accepting the lot also increases. B. As the fraction defective decreases, the probability of accepting the lot also decreases. C. As the lot tolerance percent defective decreases, the consumer's risk also decreases. D. As the AQL decreases, the producer's risk also decreases.

D. As the AQL decreases, the producer's risk also decreases.

Step-by-step explanation:

The characteristic curve is the graph that shows the relation between two variables.

Operating characteristic curve helps in the selection of sampling plans  that are effective in reducing risks.

In case of an operating characteristic curve, as the AQL decreases, the producer's risk also decreases.

Option D is correct

step-by-step explanation: yes

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
