M1A3(b)-MATH142-2_10222X +webassign.netEach front tire on a particular type of vehicle is supposed to be filled to a pressure of 27 psi. Suppose the actual air pressure in each tire is a random variable, X for the right tire and y forthe left tire, with joint pdff(z,y) = {K (x² + y²)20≤x≤ 30, 20 ≤ y ≤ 30otherwise(a) What is the value of K? (Enter your answer as a fraction.)K=(b) What is the probability that both tires are underfilled? (Round your answer to four decimal places.)(c) What is the probability that the difference in air pressure between the two tires is at most 2 psi? (Round your answer to four decimal places.)(d) Determine the (marginal) distribution of air pressure in the right tire alone.for 20 < x < 30(e) Are X and Y independent rv's?OYes, f(x,y) = fx(x) fy(y), so X and Y are independent.Ores, f(x,y) + fx(x) fy(y), so X and Y are independent.•ONO, f(x,y) = fx(x) fy(y), so X and Y are not independent.No, f(x,y) + fx(x) fy(y), so X and Y are not independent.

An instructor for a test preparation course claims that the course will improve the test scores of students. The table shows the critical reading scores for 14 students the first two times they took the test. Before taking the test for the second time, the students took the instructor's course to try to improve their critical reading test scores. At a = 0.01, is there enough evidence to support the instructor's claim? Complete parts (a) through (f).
