The practical range is all whole numbers from 480 to 1200, inclusive <u>Explanation:</u>
Given :
Clarence sells the yearly subscriptions to a particular magazine and he sells atleast 10 subscriptions and they wont be more than 25 subscriptions in an each week.
If the function
f(t)=48 t
represents the amount of money earned for selling t subscriptions each week,
f(t) = 48 (10) =480
f(t) = 48(25) = 1200
the practical range of this function will be the set of all whole numbers including 480 to 1200
Find the marginal density for by integrating the joint PDF over all possible values of :
Then the density of conditioned on is
for and undefined elsewhere.
Thus
