On Wed, 25 Oct 2000, Wolfgang Rolke asked: I am wondering how they find the Sampling error of +/-4% pts. The usual estimate for the standard error of a binomial would be (for Bush) SQRT(0.46*(1-0.46)/769) = 0.01797 The error in a 95% CI would then be 1.96*0.01797 = 3.5% and in a 99%

Wolfgang, Even if we use a binomial prob. value of 0.5 (under null hypothesis), we will get 3.5% error at 95% CI. Maybe, they are rounding up to 4%! Siddeek Wolfgang Rolke wrote: Today the following polling results were given on cnn.com for the Presidential race: CNN/USA TODAY/GALLUP POLL

A Poisson arrival process implies that the inter-arrival times are independent, and identically exponentially distributed. It IS a characteristic of the exponential distribution that the are more small values than large ones. The expected number of arrivals in any period of length t is
