Document Summary
Chapter 5 & 6 discrete & continuous probability. Variance"s shortcut formula: x 2 p(x) - 2 ; Standard deviation: x 2 p(x) - 2. Z-test & t-test; sample size & error margin. Planning value: when we don"t know the p*, so we assume it is 0. 5 for all possible values. Know the 7 steps to solve the hypothesis for full marks. P-value analysis: remember to or by 2 if it"s 1 or 2 tail(s) X2-test; hypothesis for goodness of fit: one-way table (cid:0) The 4 assumptions (for sure will fall on the mcqs) Test for significance: ho: 1= 0 vs. ha: 1 0 . R2 = ssr/sst; sst= sse + ssr; r2 (cid:224) y explained by x . Standard error of the estimate = sqrt(mse) = s. Standard error of the slope = sb1. Anova table (cid:0) know how to calculate every variable. T-test vs. f-test (cid:0) df = n-k-1.
