The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is less than 51.5 min, P(X < 51.5) = _______
Refer to the continuous uniform distribution is given. Assume that a class length between 50.0 min and 52.0 min. is randomly selected, and find the probability that the given time. (a) Less than 51.5 min (b) exactly equal to 50.9
The duration of a professor's class has continuous uniform distribution between 49.2 minutes and 55.5 minutes. If one class is randomly selected and the probability that the duration of the class is longer than a certain number of minutes is 0.279, then find the duration of the randomly selected class, i.e., if P(x>c)= 0.279, then find c, where c is the duration of the randomly selected class. THEN Round your answer to one decimal place. c = ? minutes
