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 and Y for the left tire, the joint pdf
??,?(?,?)= ?(?^2 +?^?) ?? ?? ≤?≤ ??, ?? ≤?≤ ??

? ; ?????????

Where K is 3/380,000.

(a) What is the probability that both tires are underfilled (i.e. less than or equal to 26 psi)?

(b) What is marginal distribution of air pressure in the right tire alone?

(c) When Lisa checked, her right tire was at 25 psi. What is the probability density function of her left tire pressure knowing this?

(d) Are pressure tires of right and left (X, Y) independent? Prove independence/dependence.

Your mechanic estimates that the total weight of a filled tire for your particular vehicle is less than 20 pounds. Suppose that the total tire weight for vehicles that have your particular sized tire is normally distributed with standard deviation (s) 1.25 pounds. A random sample of 55 tires (similar in size to yours) has a sample mean weight of 18.75 pounds.    Use the “4-Step Process As Applied to Tests of Significance” to test your mechanic’s claim at the 0.01...
