These questions come after the 2nd picture

(b) How many total firstborn babies were there? (Enter your answer rounded to the nearest whole number.)

firstborn babies:

(c) By hand, make a histogram and using this histogram select the correct description of the age at which women have their first child.

The distribution is:

(d) In which age classes do the median and quartiles fall in the ordered list of all maternal ages?

Median falls within:

Q1 falls within:

Q3 falls within:

(a) For comparison with other years and with other countries, we prefer
a histogram of the percents in each age class. A histogram of the percents in each age class is best to use for
comparison with other years and other countries because a histogram can only be made using percents.
O a histogram of the percents in each age class. A histogram of the percents in each age class is best to use for
comparison with other years and other countries because if different years and countries have very different
numbers of babies born, the distributions across age group will be difficult to compare because the scale will be
determined by the larger counts.
O a histogram of the counts in each age class. A histogram of the counts in each age class is best to use for comparison
with other years and other countries because if different years and countries have very different percentages of
babies born, the distributions across age group will be difficult to compare because the scale will be determined by
the larger percentages.
O a histogram of the counts in each age class. A histogram of the counts in each age class is best to use for comparison
with other years and other countries because a histogram can only be made using counts.

How old are women when they have their first child? The table displays the distribution of the age of the mother for all
firstborn children in the United States in 2014.

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.

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
