c. Construct a relative frequency polygon of amounts spent on prenatal care. Use ruler and the graph below to construct your answer. Note: In addition to labeling the axes correctly, indicate the relative frequency at each point on the polygon.

d. Construct a percentage ogive of amount spent on prenatal care. Use ruler and the graph below to construct your answer. Note: In addition to labeling the axes correctly, indicate the cumulative percentage at each point on the ogive.

e.. Does the frequency polygon suggest skewness in the data? If so, in which direction?

f. What percentage of mothers spent less than $200 on prenatal care

The amount a mother spends on prenatal care can have a long-term impact in terms of reducing complications resulting from a baby's low birth weight. A random sample of 50 new mothers was asked to estimate how much they spent on prenatal care. The results are presented in the frequency distribution below. Amount Spent on Prenatal Care ($) 0-99 100-199 200-299 300-399 400-499 Total Mothers (Number) 2 4 8 20 16 50 a. Calculate the mean amount spent on prenatal care. b. Use the short-cut formula to calculate the standard deviation of amounts spent on prenatal care.
