For each probability and percentile problem, draw the picture.

A subway train on the Red Line arrives every 7 minutes during rush hour. We are interested in the length of time a commuter must wait for a train to arrive. The time follows a uniform distribution.

State "70% of commuters wait more than how long for the train?" in a probability question. (Enter your answer to one decimal place.)

Find the probability that the commuter waits more than 2.1 minutes.

find the probability. (Enter your answer to one decimal place.)

2.State "P(19 < X < 55) = ___" in a probability question.

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 95 95 trains to arrive. Assume wait times are independent Use the Normal approximation to the Binomial distribution (with continuity correction) to find the probability (to 2 decimal places) that 56 or more of the 95 wait times recorded exceed 5minutes
