A random variable X is exponentially distributed with a mean of 0.25. 2-1. What is the rate parameter A? (Round your answer to 3 decimal places.) Rate parameter a-2. What is the standard deviation of X? (Round your answer to 2 decimal places.) Standard deviation X b. Compute PX>0.32). (Round Intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.) PX>0.32) c. Compute PO.25 S XS 0.32). (Round Intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.) P(0.25 SX 50.32)
