Part 1: Correlation and Linear Regression It is widely believed that the more education one receives the higher the income earned over the course of a career. However, du to varying reasons, many people never complete their high-school diploma or GED. Although individuals without a high-school diploma are often able to find employment, they experience economic outcomes quite different from those who finish high schoo before entering the workforce. 1. Use technology to create and provide a scatterplot of the relationship between the "percent of people in poverty" and th "percent of population 25 years and over with no high school diploma" data for each jurisdiction. Write at least two (2) sentences explaining how/why it is appropriate to create such a scatterplot and describe the characteristics of the association seen in the scatterplot. 2. Be sure to use the actual names of the variables in their appropriate places in your response(s). (Print or copy-and-paste the scatterplot and be sure to clearly identify the predictor and response variables based on the possible believed association.) Use technology to find the regression equation for the linear association between the "percent of people in poverty" and the "percent of population 25 years and over with no high school diploma." (Round final values to two decimal places.) Provide this equation. 2 Babe Write a brief interpretation (1-2 sentences) of the slope using the variable names. Gand (Print or copy-and-paste the printout that identified the equation of the linear regression line, or any other form of evidence that technology was used.) 3. A fellow student states that a decrease in the "percent of population 25 years and over with no high school diploma" wil lead to a decrease in the "percent of people in poverty." Write at least two (2) concise sentences in a response to the student's statement, being sure to address the key uses of linear correlation and comment on its limitations.
