On average when literacy rates in a population are zero the fertility rate in the population is 7.63 and when the literacy rate is 100% the fertility rate is 2.42.

(a)On a figure with female literacy on the vertical axis and fertility on the horizontal axis, draw a graph assuming a linear relationship. Referring to the linear relationship, if the literacy rate is 60%, what would be the fertility rate (approximately)?

(b)A large cost of having a baby is the time that the mother must invest to bear and rear the child. For a more educated woman, is the value of this time higher or lower, explain?

(c)In the chart, mark "cost of child" on the vertical axis. Does the trend line have any relation to a demand curve? Please explain.

(d)Please give an alternative explanation of the figure: Use the fertility rate to explain female literacy.

(e) Explain the fertility level according to marginal analysis,
