In a biomedical research study, it was determined that the survival time, in weeks, of an animal subjected to a certain exposure of gamma radiation has a gamma distribution with a = 5 and ß = 10. (a) What is the mean survival time of a randomly selected animal of the type used in the experiment? (b) What is the standard deviation of survival time? (c) What is the probability that an animal survives more than 30 weeks?
