STAT 2004 WEEK 13 Central limit theorem- No matter the observation distribution, for a large n, x bar ~ N (mu, standard error.) (x bar follows a normal distribution) o This math won’t be tested, but the concept is important. T-distribution- Has more outliers. Handle problems the same way you would handle a normal distribution, but use the t-table chart. o Degrees of freedom- How many pieces of info It is equal to n-1, and follows the t when written in distribution. For example, if it had 7 degrees of freedom the distribution would be written as t17(mu, S.E.). The rest of the lecture was essentially going over the hypotheses again. If you are still hav
