1. In 2019, the American Community Survey released the following data for the percent population aged 16 and over in the labor force and the percent population living below the poverty rate in a sample of 11 Midwest states.

State Population in Poverty (%) Population 16 and over in the labor Force (%)
Illinois 11.5 65.1
Indiana 11.9 64.0
Iowa 11.2 66.9
Michigan 13.0 61.9
Minnesota 9.0 69.5
Missouri 12.9 62.6
Nebraska 9.9 69.5
North Dakota 10.6 70.4
Ohio 13.1 63.5
South Dakota 11.9 67.9
Wisconsin 10.4 65.9

a) Each pair of data values corresponds to one __________________.

b) Use this data to create a scatterplot on graph paper.

c) State whether the variables appear to be correlated, and if so, state whether the correlation is positive or

negative. If there is a correlation, state whether it is strong, moderate or weak. Use only the pattern of the points in the scatterplot to explain your response - no context should be used.

d) Use a well-written contextual sentence to summarize any conclusions that you can draw about the relationship between these two variables based on the scatterplot. Your sentence should be directed at a general audience - do not talk about the scatterplot or use technical terms, just describe the contextual relationship.

e) Suggest a reason, other than coincidence, for the correlation or lack of correlation in this data. If you choose common underlying cause be sure to specify one.
