The following data shows the height children with time: Age X, in 18 19 20 21 22 23 24 25 26 27 28 29 (months) Height Y, in 76.1 77.0 78.1 78.2 78.8 79.7 79.9 81.1 81.2 81.8 82.8 83.5 ( cm) The regression equation, correct to 3 decimal place is Drag and drop the correct answer. Y = 0.517X + 55.876 Y = 0.669X + 62.216 Y = 0.688X + 63.927 Y = 0.635X + 64.928The following data shows the height children with time: Age X, in 18 19 20 21 22 23 24 25 26 27 28 29 (months) Height Y, in 76.1 77.0 78.1 78.2 78.8 79.7 79.9 81.1 81.2 81.8 82.8 83.5 ( cm) Find, the test statistic to the nearest whole number
