Question

The American Community Survey is a survey that uses U.S. census data to compile information on various characteristics of the U.S. population. Here are statistics that I would like you to analyze from a sample of states.

The independent variable (x-variable) is the percent of the state population living below the poverty level. The dependent variable (y-variable) is the state infant mortality rate in deaths per 1000 births. The data is displayed in the following table:

State:	Percent of Population living below poverty level	Infant Mortality Rate Deaths per 1000 Births
Vermont	11.5	5.12
New Jersey	10.2	5.35
Georgia	19.1	8.02
Kentucky	19.1	7.04
Iowa	12.8	5.43
Kansas	13.8	7.50
Colorado	13.5	6.04
New Mexico	21.5	5.81
Arizona	19.0	6.54
California	16.6	5.12
Oregon	17.5	5.41
North Dakota	12.2	6.44
Ohio	16.4	7.74
Maine	14.1	6.04
Mississippi	22.6	10.16
Arkansas	19.5	7.89
Louisiana	20.4	9.38
Wisconsin	13.1	6.57
Connecticut	10.9	6.27
Wyoming	11.3	7.05

Enter the “Poverty Rate” data into L1 and “Mortality Rate” data into L2. Carefully check all your values before you proceed with your analysis.

  

1. Use your calculator to fit a linear model to the data and store the equation in Y1. Store the predictions in L3 and the Residuals in L4.

	a.	y-hat   = 0.616 + 0.785x
	b.	y-hat   = 6.117 + 0.20486x
	c.	y-hat   = 3.5184 + 0.20486x
	d.	y-hat = 15.223 + 4.375x
	e.	y-hat  = 0.785 + 3.51846x

Answer 1

so the correct regressionline is option C
