pavelcherepan Posted February 10, 2019 Share Posted February 10, 2019 (edited) Hi all! This is not a homework question, just a silly thing I've been working on. I have a set of 11 random variables and one constant (that I don't know the value of). Every time I run an experiment all 11 variables assume a value of either 0 or 1 (all together). The question is simple: how to calculate the total number of experiments that I need to do in order for the average value of those 11 variables (from all experiments) to approach the mean of 0.5 to an accuracy of, let's say, 99.9%. After that I should be able to find out the value of my constant. Thanks for the help! Edited February 10, 2019 by pavelcherepan Link to comment Share on other sites More sharing options...
Bignose Posted February 11, 2019 Share Posted February 11, 2019 If all 11 variables and all experiments are independent and identically distributed, then you can use the binomial distribution to calculate what you need https://en.wikipedia.org/wiki/Binomial_distribution Link to comment Share on other sites More sharing options...
