hospitalization period

2.66    The hospitalization period, in days, for patients following treatment for a certain type of kidney disor- der is a random variable Y = X + 4, where X has the density function

 

 

 

2.61    Assume that two random variables (X, Y ) are uniformly distributed on a circle with radius a. Then the joint probability density function is

 

 

f (x) =

 

(x+4)3 ,   x > 0,

 

( 32 0,           elsewhere.

 

 

 

2f (x, y) =

 

 

, x     1                2

 

Ï€a2

 

 

+ y2

 

≤ a ,

 

Find the average number of days that a person is hos- pitalized following treatment for this disorder.

 

0,       otherwise.

 

 

 

Find μX , the expected value of X.

 

 

 

2.62    Find the proportion X of individuals who can be expected to respond to a certain mail-order solicitation if X has the density function

 

2.67    Suppose that X and Y have the following joint probability function:

 

 

 

f (x) =

 

( 2(x+2)
