Please 77. A subway train on the 4 line arrives every sight minutes during rush hour....
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...
Problem 1 A subway train on the #5 line arrives every eight minutes. We are interested in the length of time a commuter must wait for a train to arrive. The time follows a uniform distribution In each appropriate box you are to enter either a rational number in "p/" format or a decimal value accurate to the nearest 0.01 a. The waiting time is modeled by a random variable X with X (pick on distribution b. The density function...
A bus arrives every 11 minutes to a stop. The waiting time for a particular individual is assumed to be a random variable with uniform continuous distribution. What is the probability that the individual waits for more than 6 minutes? Answer using 4 decimals.
A bus comes by every 14 minutes. The times from when a person arives at the busstop until the bus arrives follows a Uniform distribution from 0 to 14 minutes. A person arrives at the bus stop at a randomly selected time. Round to 4 decimal places where possible. c. The probability that the person will wait more than 4 minutes is _____ d. Suppose that the person has already been waiting for 0.5 minutes. Find the probability that the...
A bus comes by every 15 minutes. The times from when a person arives at the busstop until the bus arrives follows a Uniform distribution from 0 to 15 minutes. A person arrives at the bus stop at a randomly selected time. Round to 4 decimal places where possible. a. The mean of this distribution is b. The standard deviation is c. The probability that the person will wait more than 5 minutes is d. Suppose that the person has...
A bus comes by every 13 minutes. The times from when a person arives at the busstop until the bus arrives follows a Uniform distribution from 0 to 13 minutes. A person arrives at the bus stop at a randomly selected time. Round to 4 decimal places where possible. a. The mean of this distribution is b. The standard deviation is ? c. The probability that the person will wait more than 7 minutes is ? d. Suppose that the...

2. The University of Southwest Arizona provides bus transportation services to students while they are on campus. A bus arrives at the North Main Street and College Drive stop every 30 minutes, between 6 in the morning and 11 at night during the week. Students arrive at the stop at random times. The time a student waits has a uniform distribution of 0 to 30 minutes. A. Draw a graph of the distribution. B. Show that the area of this...
Currently the bus runs every 7 minutes during the day. Let X represent the amount of time Sofia waits for the bus, assuming she arrives at the bus stop at a random time and the bus is running on schedule. (That is, the amount of time Sofia waits is uniformly distributed.) Find the following probabilities (use 2 decimal places for all answers): (a) The probability Sofia waits at most 2 minute(s) = (b) The probability Sofia waits less than 2...
Can someone explain all these questions? B5. In order to go to university a student needs to catch a train at 8:41a.m. every morning. Cycling to the station from home takes the student on average 14 minutes, with a standard deviation of 3 minutes. You can assume that the distribution of trip times is normally distributed and independent between days i) What is the probability that the student's cycle ride to the station will take more than 21 4 marks...
