The highest and lowest birth rates in the United States in 2010
were in Utah and Maine, respectively. Utah reported 52,258 births
with a population of about 2.8 million people. Maine reported
12,970 births with a population of about 1.3 million people. Use
this data to answer the following questions.
a) On average, how many people were born each day of the year in
Utah?
b) On average, how many people were born each day of the year in
Maine?...

a relative frequency histogram for the data (use k = 5 intervals
!!!), b) Construct a cumulative relative frequency histogram (an
empirical distribution function), c) Using grouped data estimate

#$Last, the researchers hopes to understand how
GDP influence birth rates. They theorize that perhaps countries
with higher gross domestic product will invest more in women’s
schooling. If more women know how to read, they hypothesize, then
those women may have fewer children (due to better birth control
knowledge, higher career aspirations, etc). The researchers add a
variable measuring the percentage of women who can read to the
regression equation. The results are presented in Equation 3 of
Table 1....

The World Bank has data on savings rates and GDP growth rates
for most countries of the world. Download the data and create a
scatter plot between those two variables for 2019. Is there an
obvious relationship between growth rates and savings rate? Explain
why you might see what you observe.

In the data from the text, we observe that countries with high
inflation rates tend to
have high nominal interest rates. What does this imply, if
anything, about real interest
rates in countries with very high inflation rates?
“Convergence in growth rates and income per capita across the
different countries is a necessary outcome expected by both the
neoclassical Solow growth model and the endogenous growth theory.
“Is this statement true? (Discuss the issue by giving references to
the fundamental premises of these two theories). Looking at the
real-life data, has the convergence hypothesis been validated in
the world? Explain.
