Let I be the number of days for a randomly selected trial. Round all answers to 4 decimal places where possible. a. What is the distribution of I? I v N[:],:]} b. If one of the trials is randomly.r chosen, find the probabilityr that it lasted at least 14 days. C] c. If one of the trials is randomly.r chosen, find the probability.r that it lasted between 1? and 21 days. :1 d. 9096 of all of these types of trials are completed within how many.r days?
