Q4

Each front tire on a particular type of vehicle is supposed to be filled to a pressure of 26 psi. Suppose the actual air pressure in each tire is a random variable-X for the right tire and Y for the left tire, with joint pdf
[K(x² + y²) 20 ≤ x ≤ 30, 20 ≤ y ≤ 30
=
f(x, y) =
otherwise
(a) Determine the conditional pdf of Y given that X = x.
fy|x(y|x) =
for 20 ≤ y ≤ 30
Determine the conditional pdf of X given that Y = y.
fx|x(xly) =
for 20 ≤ x ≤ 30
Round your answer to three decimal places.)
(b) If the pressure in the right tire is found to be 22 psi, what is the probability that the left tire has a pressure of at least 25 psi? (It is known that K =
380,000
Compare this to P(Y≥ 25). (Round your answer to three decimal places.)
P(Y ≥ 25) =
(c) If the pressure in the right tire is found to be 22 psi, what is the expected pressure in the left tire, and what is the standard deviation of pressure in this tire? (It is known that K =
