Once an individual has been infected with a certain disease, let X represent the time (days) that elapses before the individual becomes infectious. An article proposes a Weibull distribution with a = 2.6, ß= 1.7, and y = 0.5. [Hint: The two-parameter Weibull distribution can be generalized by introducing a third parameter y, called a threshold or location parameter: replace x in the equation below, ²²-1-(x/B)a f(x; a, B) = Ba" 0 x20 x < 0 by xy and x 20 by x 2 y.] (a) Calculate P(1 < X < 2). (Round your answer to four decimal places.) 0.4737 (b) Calculate P(X> 1.5). (Round your answer to four decimal places.) 0.7775 (c) What is the 90th percentile of the distribution? (Round your answer to three decimal places.) 2.843 ✔ days (d) What are the mean and standard deviation of X? (Round your answers to three decimal places.) 1.496 X days mean
