Problem 1 graphs and tables about the diabetes in the United

Problem 1. graphs and tables about the diabetes in the United States population. You may have read or heard people talking about the \"diabetes epidemic\" that has resulted in much suffering and millions of dollars in health care expenses. Please answer the following questions about these graphs and tables as you explore possible causes of this \"diabetes epidemic\". Number (in Millions) of Persons with Diagnosed Diabetes, United States, 1980-2007 18 16 14 12 1980 1985 1990 1995 2000 2005 Source: Centers for Disease Control and Prevention 2007 5.Numbers of people diagnosed with Diabetes in the United States, 1980- When you show this graph to one of your friends, he says that the explanation for the increased number ofindividuals with diabetes is simple, more people have been diagnosed with diabetes in 2007 than in 1980 because the total population size of the United States increased during that time interval. A. How could you determine if your friend\'s explanation is correct or not? According to the US Census Bureau, the population of the United States increased from 226.5 million in 1980 308.7 million in 2010. During the intervening decades, the population increase was 222 32.7 and million, B. Use respectively. 5 to fill in Table 1 below. You will this information and the information in Figure need to extrapolate the line in Figure 5 to the year 2010. population diagnosed Year TPopulation sze, TNumber diagnosed wth TRof melnus diabetes mellitus (in miions) diabetes 1980 1990 2000 2010 and percentage of that population Table 1. United States population size diagnosed with diabetes, 1980 to 2010

Solution

A) To determine if the increase in number of people diagnosed with diabetes is because of the increase in population of diabetes over the years, we need data about the population of United states over the years from 1980 to 2007. We can use this data to calculate the percentage of population diagnosed with diabetes for each year -(Number of individuals diagnosed with diabetes for a particular year / Population of United states for that particular year) * 100. This percentage should remain constant if the friend\'s suggestion is correct.

B)

Population size

(in Millions)

Number of individuals diagnosed with Diabetes Mellitus

(in Millions)

The population size for 1980 and 2010 are given. For 1990 and 2000, it is calculated by adding the increase in population to the previous decade\'s population. For 1990, it is 226.5+22.2=248.7 and for 2000, it is 248.7+32.7=281.4

The number of individuals is obtained by determining the y-axis intercepts for the specific years given on the x-axis

The % of population = (Number of individuals diagnosed with diabetes for a particular year / Population of United states for that particular year) * 100

For 1980, (5.5/226.5)*100=2.4%

For 1990, (7/248.7)*100=2.8%

For 2000, (13/281.4)*100=4.5%

For 2010, (21/308.7)*100=6.8%

C) Friend\'s statement does not hold true since the percentage of population diagnosed with diabetes shows an increase as well.

D) The increase could be due to better diagnostic facilities available, which results in more people being diagnosed over the years!

Year	Population size (in Millions)	Number of individuals diagnosed with Diabetes Mellitus (in Millions)	% of population diagnosed with Diabetes Mellitus
1980	226.5	5.5	2.4
1990	248.7	7	2.8
2000	281.4	13	4.5
2010	308.7	21	6.8
