(1 point) The amounts (X) of 6 restaurant bills and the corresponding amounts (y) of the tips are given in the table below. Bill 64.30 43.58 32.98 106.27 70.29 97.34 Find the following: The regression equation is = Tip 7.70 5.50 4.50 16.00 10.00 16.00 + x. If the amount of the bill is $80, the best prediction for the amount of the tip is (1 point) For the (x,y) data set (-3, 3), (1, 3), (5, 4), (9, 6), (9, 12), find interval estimates (at a 98% confidence level) for single value and for the mean value of y corresponding to x = 8. Note: For each part below, your answer should use interval notation (lower limit, upper limit). Interval Estimate for Single Value = Interval Estimate for Mean Value = (1 point) The amounts (X) of 6 restaurant bills and the corresponding amounts (y) of the tips are given in the table below.
