(HINT: First, you need to determine the sign of the slope of corresponding regression equation!) Answer: Question 17 Not yet answered You are given the following information about y and x: Points out of 1.00 y x Dependent Variable Independent Variable Flag question 12 4 3 6 7 2 6 4 Furthermore, regression analysis between these two variables resulted in the following estimated regression equation: y = 11 - x Calculate the correlation coefficient r; round your answer to three decimal places. Answer: A regression analysis between sales (y in $1000) and advertising (x in $100) resulted in the following estimated regression equation: = 80+ 6.2x Based on the above equation, if advertising is $10,000, then the estimated value for sales is
