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 37.5 ins and standarddeviation 21.6 (suggested by the article "computation time of grid computing with data transfer times that follow agamma distribution.‘ proceedings of the first international conference on semantics, knowledge. and grid, 2005).a. what are the values of a and p? b. what is the probability that data transfer time exceeds 50 ms? c. what is the probability that data transfer time is between 50 and 75 ms?
