Answer:
700 lbs and 3.742
Step-by-step explanation:
Given that raw materials are studied for contamination. Suppose that the number of particles of contamination per pound of material is a Poisson random variable with a mean of 0.02 particle per pound.
a) To get 14 particles of contamination we must have
expected number of pounds =
b) Since for 700 pounds particles expected are 14 we can say in a Poisson distribution mean and variance are equal
i.e. Var (700 lbs to obtain 14 particles of contamination ) = 14
Std deviation =
Now all you have to do is divide -3x by -2 and 18 by -2 which would be:
Y= 3/2x-9
Y= 3/2x-9
