15 Projected undernourished individuals. In 2020, TheFAO, IFAD, UNICEF, WFP, and WHO published a brief....NOURISH report on the state of food security and nutrition in theworld. There were 687.8 million undernourished peoplein the world in 2019. One of the sections in the reportshows the distribution of these people as shown in thefollowing table:RegionAfricaAsiaNorthern America and EuropeOceaniaLatin America and the CaribbeanPercentageof undernourishedpeople (%)36.455.40.90.46.9a. Describe the variable measured in the table.b. These results were displayed in the form of a pie chart.Reconstruct the pie chart from the information given inthe table.c. How many of the 687.8 million undernourished peoplein the world in 2019 were in Africa?d. As Africa has many third world countries, people mightexpect Africa to have the highest number of undernour-ished people in the world. Does the information in thepie chart, part b, support this contention? Explain whyor why not.
