Once an individual has been infected with a certain disease, let X represent the time (days) that captes before the individual becomes infectious. An article proposes a webol distribution with - 2.6, 1-1.2. and y=0.5.(Hint: The two-parameter Weibull distribution can be generalized by introducing a third parametery, called a threshold or location parameter: replace in the equation below 1-x20 X; , - 0 x by and x 20 byx (0) Calculate IX 1.5). (Round your answer to four decimal place) (c) What is the son percentile of the astribution (Round your answer to three decimal places) days (a) What are the mean and standard deviation of X? (Round your answers to three decimal pact) mean days standard deviation days
