Statistics help please. So I'm give the mean of x= 119, S.D. of x= 10, mean of y= 1.30, S.D.of y=0.55
Sally obtained a score of 130 on x-variable. Predict her score on the y-variable (I think i did this but I'm unsure). A score of 1.28 on the y variable was predicted for Bill. What was his score on the x-variable? (again I think I did this but feel really unsure)
Determine the standard error of estimate for Y. (this is where I get really lost, isn't standard error of estimate sqrt[ (y- ^y(y with the hat))^2/n-2] but i only have 2 scores, I think I am missing some major things in my notes)
