Question

Question 1 (6 points) You are given the following information about the data set containing variables y and x: $\bar{y}$ = 6.7, $\bar{x}$ = 4.9 The least squares method yields the following value for the slope of estimated regression equation: b? = -2.2 Find the estimated value of y when x = 12.3; show your answer with two decimal places (HINT: You need to start with the regression equation)
