Description: NOTE ERROR: 3rd example should be sqrt(100) (not sqrt(10)) Visit ilectureonline.com for more math and science lectures! To donate: ilectureonline.com/donate patreon.com/user?u=3236071 We will learn how does the sample size affect hypothesis testing? The test statistic is proportional to SQRT(sample size). A greater sample size increases the probability that the sample statistic will fall in the critical region BUT it will also reduce random variability in the mean of the sample.
