Zy is the predicted z-score for the y variable. Zx is the z-score for a particular raw score on the x variable. **exam will give you my, mx, sdy, sdx, rxy r2 (error/ variability in y) Fill in all x and y scores from original data. Use the raw score regression model to calculate y. The sum of all the y-y"s will =0. The sum of the (y-y)2"s is the sse. Sst is the sum of all the (y-m)2 (y minus the mean of y and then squared) r2= sst-sse. Z-score= 1. 5, appendix a tells us that 43. 32% are between the mean and 1. 5. The percent below 1. 5 is 43. 42 (b) + 50 (a)= 93. 32% Null= h0: 1 +/-/= 2 (the symbol will be the opposite of that in the research hypothesis. The z-score that corresponds to the start of the alpha region, use the z table to find zcrit for a given alpha.
