Suppose the rate of change of the percentage of low-birthweight babies (less than 5 pounds 8 ounces) in 2000 can be modeled by percentage points per pound when the mother gains w pounds during pregnancy. The model is valid for the weights between 18 and 43 pounds. Estimate, to two decimal places, the area of the region between the graph of P and the w-axis from to using 5 midpoint rectangles. Interpret your answer.
A) In 2000, there was a 12.41% decrease in the number of low-birthweight babies whose mothers gained between 18 and 43 pounds.
B) In 2000, there was a 6.60% increase in the number of low-birthweight babies whose mothers gained between 18 and 43 pounds.
C) In 2000, there was a 4.27% decrease in the number of low-birthweight babies whose mothers gained between 18 and 43 pounds.
D) In 2000, there was a 3.58% increase in the number of low-birthweight babies whose mothers gained between 18 and 43 pounds.
E) In 2000, there was a 2.76% decrease in the number of low-birthweight babies whose mothers gained between 18 and 43 pounds.
