Question

If the size of each step is about 1 meter , what is the standard deviation in meters for the simulated walks taken by the 20 drunks ?

What is the standard deviation of the mean (SDM) for the simulated walks taken by the 20 drunks ?

Answer 1

I did the simulated walks on Excel

Answer 2

need more info..what is original question?

Answer 3

did you open the attachments?

Answer 4

yes based on your simulation...you are assuming a uniform distribution from 0 to 1 for each step
why do you do 3*step - 1 ??

Answer 5

to determine a std dev without data you need to know the type of distribution
"about 1 meter" is vague, does it vary from 0 to 1 or .5 to 1.5 ?

Answer 6

SDM = s/sqrt(n) = s/sqrt(20)

Answer 7

idk I'm confused. first question was list the location of each of the 20 drunks in "steps" right(+) or left(-) from the bar.

so I said 9 steps to the right
6 steps to the left ???????????

Answer 8

how did you get that? there must be more info about the steps than "about 1 meter" please post entire problem with instructions and all info

Answer 9

it seems like you are to assume 1 meter = 1 step and a "walk" consists of a num of steps in random directions

Answer 10

i gotta go...if you post entire problem i will look at it later and try to post a solution for you

Answer 11

there is no more info about the steps. first it asked me to do the spreadsheet simulation (random)

Answer 12

ok thannks.)
