- During a professor's office hours, students arrive, on average, every ten minutes. Assume that the distribution of the time between arrivals follows an exponential distribution. Suppose that a student has just left. Suppose that a student has just left. Only 25% of the time will the professor have to wait approximately how long or longer before the next student shows up?The arrival of an item ordered in Amazon is assumed to follow the exponential distribution with parameter λ. On average, the item is expected to arrive in 2 days. Calculate λ. What is the probability that you will receive the item within the first 24 hours? What is the probability that the item will arrive late after 5 days?The following graph plots the fitted probabilities of default (y axis) depending on the credit balance (x axis) with the linear probability model (left) and the logistic model (right). Which alternative is NOT correct 500 1000 1500 2000 2500 500 1000 1500 2000 2500 Balance Balance O a. There will always be a balance level such that the probability of default according to the linear probability model is above 100% O b. The logit model supposes that the error term of the latent variable follows a logistic distribution O C. The linear probability model estimates probabilities of default below 0% Od. The probability of default lower than 50% is a frequent feature of linear probability models e. The logistic model estimates probabilities between 0% and 100% 00 80 90 YO 0 Probability of Default R'O 90 o zo o'o Probability of Default
