Question 1: Consider a simple normal linear regression model Y = ̢̢̢ + ̢̢X + ̢ with the usual assumptions. For testing the hypothesis H0 : ̢̢ = 0 versus Ha : ̢̢ ≠ 0, we discussed three possible tests procedures: 1. Overall F test 2. Individual t test 3. Correlation t test Show that Fobs = t"obs = tc,obs".

Assume that we have a regression model: y = bo + b1x If we have an observation with a Zx equal to -0.60, and the correlation coefficient is r = -0.50, how many standard deviations do you expect the predicted value for the response variable (y) to be above or below the mean? (Enter a positive number if it will be above the mean, a negative number if it will be below the mean, and 0 if it will be right at the mean): Note: 1- Only round your final answer to 2 decimal places. Enter your final answer with 2 decimal places.
