Question
The weight (in pounds) and height (in inches) for a child were measured every few months over a two-year period. The results are given in the table. Using technology, what is the slope of the least- squares regression line and what is its interpretation? The slope is 1.98, which means for each additional inch in height, the child's weight will increase by 1.98 pounds. Weight (x) 12 18 24 30 32 35 37 40 Height (y) 22 23 26 30 32 33 35 36 38 The slope is 1.98, which means for each additional inch in height, the child's weight is predicted to increase by 1.98 pounds. O The slope is 0.50, which means for each additional pound in weight, the child's height will increase by 0.5 inches. O The slope is 0.50, which means for each additional pound in weight, the child's height is predicted to increase by 0.5 inches.
