Need help with part (b). may use excel

In part (a) alpha is 3.0075 and beta is 1.995

Extracted text: Let X denote the data transfer time (ms) in a grid computing system (the time required for data transfer between a "worker" computer and a "master" computer). Suppose that X has a gamma distribution with mean value 6 ms and standard deviation 3.46 (suggested by the article "Computation Time of Grid Computing with Data Transfer Times that Follow a Gamma Distribution,"D). a.What are the values of a and B? (Round your answer to the nearest integer) a= B= b.What is the probability that data transfer time exceeds 20 ms? (Round your answer to four decimal places.)
