The actual tracking weight of a stereo cartridge that is set to track at 3 g on a particular changer can be regarded as a continuous rv X with the following pdf. 2 k 1 − (x − 3) 2 ≤ x ≤ 4 f(x) = 0 otherwise (d) What is the probability that the actual weight is within 0. 55 g of the prescribed weight? (Round your answer to four decimal places. ) (e) What is the probability that the actual weight differs from the prescribed weight by more than 0. 6 g? (Round your answer to four decimal places. )
