Let X denote the vibratory stress (psi) on a wind turbine blade at a particular wind speed in a wind tunnel. Use the Rayleigh distribution, with pdf. e-x²/(20²) f(x; 8) 82 0 as a model for the X distribution. (a) Verify that f(x; 8) is a legitimate pdf. 82 X>0 otherwise. e 0 (b) Suppose 8 124. What is the probability that X is at most 200? Less than 200? At least 200? (Round your answer to four decimal places.) at most 200 less than 200 at least 200 (c) What is the probability that X is between 100 and 200 (again assuming 8 124)? (Round your answer to four decimal places.) (d) Give an expression for P(X s X). P(XS X) =
