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. (1) Give the distribution of X. X~ _____ ( 0 , 7 ) (2) Find the probability that the commuter waits less than one minute. (Enter your answer as a fraction.) (3)Find the probability that the commuter waits between four and five minutes. (Enter your answer as a fraction.) (4) 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 ______ minutes. Draw the picture and find the probability. (Enter your answer to one decimal place.)
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
For each
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.
(1) Give the distribution of X. X~ _____ ( 0 , 7 )
(2) Find the probability that the commuter waits less than one minute. (Enter your answer as a fraction.)
(3)Find the probability that the commuter waits between four and five minutes. (Enter your answer as a fraction.)
(4) State "70% of commuters wait more than how long for the train?" in a probability question. (Enter your answer to one decimal place.)
