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 having trouble with these, remember that finding the p-value is a much easier way to solve the problem. If the p-value is less than alpha, reject the null hypothesis.
