the trails are just sample from some distributaion, for the treshhold # u can say its just a numer, so we are trying to prove the the output of the samples larger than 7 "treshhold" is 99.99% with 90%confience..i hope that makes it more clear

the probabilty of the treshhod # being correct, which is the 2nd trail..thanks

http://www.itl.nist.gov/div898/handbook/prc/section2/prc263.htm this can be a reference

is it that hard??

we need to show with 90% confidence that the probability of the "treshhold number" being correct is 99.99%. "So we want P=0.9999 with C=0.90". we can consider 5 trails without put { 4, 7, 12, 9, 11}..we can say the treshhold # is the "2nd trail = 7"... i tried doing it using t alpha but i failed...

i tried using the eqautaion "Confiendnce interval on the mean, varaiance known" but i am not sure how to get the variance. thanks

QUES: the yield of a chemical process is bieng studied. the past 5 days of plant operation have resulted in :91.6, 88.75, 90.08, 89.95, 91.3. Find a 95% two-sided confiendce interval. Thanks folks

lets say u consider #5 as the thresh#, and for the numbers> 5, u tryto find the confiendnce interval for 99.99% or greater. thanks

Basically u can do the confidence for 99%

Lets say you have 5 trials, and 5 output let's say {5, 43, 60, 30 , 4}...so how would u get the chi sqaure from here & the confidence interval. i haven't work on prob &statc in years, thanks a lot for help folks

well, it had 10 marbles in the 1st and 2nd urn, and 7 in the 3rd

[b]1. u have 3 urns and there are black and white marbles in each of them. if u picked a black ball..what is the probabilty it was from the second urn Homework Equations [b]3. what i did was that i thought the probailty is 1/3 since there is only 3 marbles..but i aint sure if...
