Tests.The tests that are given are not comprehensiveand passing the tests for a question does notmeanthat you answered the question correctly. Tests usually only check that your table has the correct columnlabels. However, more tests will be applied to verify the correctness of your submission in order to assignyour final score, so be careful and check your work! You might want to create your own checks along theway to see if your answers make sense. Additionally, before you submit, make sure that none of your cellstake a very long time to run (several minutes).Free Response Questions:Make sure that you put the answers to the written questions in the indicated cellwe provide. Check to make sure that you have a Gradescope()account, which iswhere the scores to the free response questions will be posted. If you do not, make sure to reach out to yourassigned (u)GSI.Advice.Develop your answers incrementally. To perform a complicated table manipulation, break it up intosteps, perform each step on a different line, give a new name to each result, and check that eachintermediate result is what you expect. You can add any additional names or functions you want to theprovided cells. Make sure that you are using distinct and meaningful variable names throughout thenotebook. Along that line, DO NOTreuse the variable names that we use when we grade your answers. Forexample, in Question 1 of the Global Poverty section, we ask you to assign an answer to latest. Do notreassign the variable name latestto anything else in your notebook, otherwise there is the chance thatour tests grade against what latestwas reassigned to.You neverhave to use just one line in this project or any others. Use intermediate variables and multiplelines as much as you would like!To get started, load datascience, numpy, plots, and ok.

Global Population GrowthThe global population of humans reached 1 billion around 1800, 3 billion around 1960, and 7 billion around2011. The potential impact of exponential population growth has concerned scientists, economists, andpoliticians alike.The UN Population Division estimates that the world population will likely continue to grow throughout the21st century, but at a slower rate, perhaps reaching 11 billion by 2100. However, the UN does not rule outscenarios of more extreme growth.(-growing-population/ft_15-06-04_popcount/)In this section, we will examine some of the factors that influence population growth and how they arechanging around the world.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
