The amount of time, in minutes, that a person must wait for a bus is uniformly distributed between 0 and 15 minutes, inclusive. 1. What is the standard deviation of the distribution? Q is normally distributed with a mean of 100 and a standard deviation of 15. 1. What is the probability that a person chosen at random has an IQ less than 80?

The amount of time it takes for a student to complete a statistics quiz is uniformly distributed (or, given by a random variable that is uniformly distributed) between 25 and 59 minutes. One student is selected at random. Find the probability of the following events. A. The student requires more than 54 minutes to complete the quiz. Probability = B. The student completes the quiz in a time between 30 and 35 minutes. Probability = C. The student completes the...
The wait time (after a scheduled arrival time) in minutes for a train to arrive is Uniformly distributed over the interval [0, 12]. You observe the wait time for the next 100 trains to arrive. Assume wait times are independent. Part a) What is the approximate probability (to 2 decimal places) that the sum of the 100 wait times you observed is between 565 and 669? Part b) What is the approximate probability (to 2 decimal places) that the average of the...
