A random variable X is exponentially distributed with an expected value of 47.

a-1. What is the rate parameter ? (Round your answer to 3 decimal places.)

a-2. What is the standard deviation of X?

Compute P(38 X 56). (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.)

c. Compute P(29 X 65). (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.)
