sul diw anoidudinisio gridinsand S Exercises 69 The number of firstborn children to mothers under 10 or over 50 years of age represent a negligible percentage of all first births and are not included in the table. (a) For comparison with other years and with other countries, we prefer a histogram of the percents in each age class rather than the counts. Explain why. (b) How many babies were there? (c) Make a histogram of the distribution, using per- cents on the vertical scale. Using this histogram, describe the distribution of the age at which women have their first child. (d) What are the locations of the median and quartiles in the ordered list of all maternal ages? In which age classes do the median and quartiles fall?
