Document Summary

Only need to know slide 22 - 25. Slide 25 (if it"s asking for mean or sd of distribution) What"s the probability of something being greater than, less than, or in between (on the bell curve) Go to table to find z score for this probability that"s your answer. If it"s asking for what"s above 61% of data you use formula z = x-u/ o. Find the z scores from tables (if you can"t find it find closest) Have to find probability greater, smaller, in between % data greater or smaller than x. Only thing different with this chapter from six is that there is probability involving sample size. Ask yourself this to know what formula from 7 to use. 2 or 3 questions where you just have to use the lower part of the sampling distribution (to find sampling error) Have to identify when you have to use z and when you have to use t.
