1.) X: 8, 6, 4, 3, 4, 5

Y: 0,1,4,6,6,1

 From the following

a. Find the linear equation for predicting Y from X.

b. Conduct a t-test to answer the question: does X significantly predict Y?

c. Calculate the standard error of estimate. What does this measure?

2.A set of n=15 pairs of X and Y values has a Pearson correlation of r=.45 and SSy=90 . If you are using the data as the basis for a regression equation,

a. Find the standard error of estimate.

b. How much error would you expect if the sample size were n=50 instead of n=15?
