Video 19: Hypothesis testing using t-distribution Previously we assumed o of our 2 fair die = 2.917 friends die = of a We can estimate of using the 2 sample variance S the consequence of this is that our test statistic variable than before is more ( two random variables 1 X and o ) test statistic no longer follows Standard normal distribution As n increases, the distribution becomes more peaked and more like the Normal Distribution X 2=~N (0,1) σ tn- -x t So if we have a sample of size n, and we estimate or by s then the test statistic has a t distribution the appropriate distribution will be determined by n S 0-1
