Question:
22. Suppose the distribution of the time X (in hours)
spent by students at a certain university on a particular project is gamma with parameters a 50 and b 2. Because a is large, it can be shown that X has approximately a normal distribution. Use this fact to compute the probability that a randomly selected student spends at most 125 hours on the project.
