The weight (in pounds) and height (in inches) for a childwere measured every few months over a two-yearperiod. 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 additionalinch in height, the child's weight will increase by 1.98pounds.Weight (x)1218243032353740Height (y)222326303233353638The slope is 1.98, which means for each additionalinch in height, the child's weight is predicted toincrease by 1.98 pounds.O The slope is 0.50, which means for each additionalpound in weight, the child's height will increase by0.5 inches.O The slope is 0.50, which means for each additionalpound in weight, the child's height is predicted toincrease by 0.5 inches.
