Data collected over time show that trains in Chicago depart on time 70% of the time. You designed a simulation to generate departure data using the numbers 0, 1, 2, 3, 4, 5, and 6 to represent on-time departures, and the numbers 7, 8, and 9 to represent departures that are not on time. Use the random number table below, starting with the first digit of the third row to generate departure data for 25 trains. Using this simulation, what percentage, rounded to the nearest whole number, of the 25 trains depart on time?

OpenStudy (collegebound2016):

This is the simulation it is talking about. The answer choices are: A)70% B)76% C)75% D)24%

Can anyone help? @Atrineas @woodyt @Directrix @DARTHVADER2900 @Azionne @braves12

OpenStudy (collegebound2016):

If you know someone can you pass this on I need hep

If you know someone can you pass this on I need help

OpenStudy (collegebound2016):

ok thank you!!! I appreciate it. Are you sure?

OpenStudy (woodyt):

Wait!

OpenStudy (collegebound2016):

Lol

OpenStudy (woodyt):

DirectX is here he's definitely gonna help you out!

OpenStudy (collegebound2016):

ok

OpenStudy (collegebound2016):

@Directrix I dont understand these questions AT ALL!!!

Directrix (directrix):

I am trying to pull up this question as solved by @jim_thompson5910 First line: Ok so here's how the table works. Each number in the table is a separate digit. The first 9 shown means that the first train is late since it says `7, 8, and 9 to represent departures that are not on time.` the next digit is 2, so the train is on time because `the numbers 0, 1, 2, 3, 4, 5, and 6 to represent on-time departures` and so on

Directrix (directrix):

`You have designed a simulation to generate departure data using the numbers 0, 1, 2, 3, 4, 5, and 6 to represent on-time departures, and 7, 8, and 9 to represent departures that are not on time. ` 9 - late 2 - on time 6 - on time 3 - on time 0 - on time ------------ 7 - late 8 - late 2 - on time 4 - on time 0 - on time ------------ keep doing this until you have done 25 trains total

Directrix (directrix):

once you've done all that work to get the 25 trains, count how many are on time and then divide that number by 25. Finally multiply that result by 100 to convert to a percentage

Directrix (directrix):

@lydiasantos how do i know when i have gotten to the 25 trains, what adds up to the 25 that is what i dont get

OpenStudy (collegebound2016):

ok

Directrix (directrix):

when you've used up 25 digits in the table (ie when you get to the end of block #5)

Directrix (directrix):

9 - late 2 - on time 6 - on time 3 - on time 0 - on time ------------ 7 - late 8 - late 2 - on time 4 - on time 0 - on time ------------ 1 on time 9 late 2 on time 6 on time 7 late ---------------- 9 late 5 on time 4 on time 5 on time 7 late ------------------ 5 on time 3 on time 4 on time 9 late 7 late

Directrix (directrix):

looks good

Directrix (directrix):

oh wow I didn't read the whole problem I skipped over the part where it says `starting with the first digit of the third row to generate departure data for 25 trains.`

OpenStudy (collegebound2016):

yes sir

Directrix (directrix):

oh boy lol me neither

Directrix (directrix):

Focus on the third row ------------ 5 - on time 9 - late 6 - on time 5 - on time 4 - on time ------------- 7 - late 1 - on time 9 - late 6 - on time 6 - on time ------------- 2 - on time 7 - late 3 - on time 8 - late 6 - on time ------------- 5 - on time 0 - on time 0 - on time 0 - on time 4 - on time ------------- 0 - on time 5 - on time 3 - on time 5 - on time 8 - late -------------

Directrix (directrix):

thanks! 19 are on time divided by 25 = .76 = 76% ??

Directrix (directrix):

you nailed it

OpenStudy (collegebound2016):

Thanks @Directrix

Directrix (directrix):

cool thanks you helped me!

Directrix (directrix):

you're welcome

OpenStudy (collegebound2016):

No problem

Sorry that I could not get the OS thread for that to come up. That info came from the cache. I don't know what "Ask Clash" is. URL: This is Google's cache of http://openstudy.askclash.com/updates /56f0aac4e4b021ce9ad2bc89. It is a snapshot of the page as it appeared on May 7, 2016 23:44:30 GMT.

To be clear, this is the work of @lydiasantos and @jim_thompson5910
