**Educational Analysis of Poverty Rate and Education Level**The dataset includes information from eleven randomly selected U.S. states, examining the relationship between the percentage of households below the poverty level (Poverty Rate) and the percentage of adults with at least a high school diploma (HS and Above).**Data Table:**- The table provides two columns: one for Poverty Rate and the other for HS and Above.- The values show the variation in poverty rates alongside the corresponding percentage of adults with high school education or higher.- Notable values include: - States with higher poverty rates (e.g., 20.1%, 17.9%) tend to have lower percentages of adults with high school education (e.g., 80.4%, 80.8%).**Scatter Plot Analysis:**- The graph shows the relationship between Poverty Rate (x-axis) and HS and Above (y-axis).- Blue dots represent each state’s data.- A downward-sloping line of best fit indicates a negative correlation. - As the Poverty Rate increases, the percentage of adults with high school education generally decreases.**Equation and Statistical Metrics:**- The line of best fit is represented by the equation: \( y = 98.74 - 1.006x \). - This suggests that for each 1% increase in Poverty Rate, the HS and Above percentage decreases by approximately 1%.- \( n = 11 \) indicates the number of data points (states).- \( s = 11.887 \) is the standard deviation.- \( r^2 = 0.81 \) signifies a strong negative correlation, implying that approximately 81% of the variation in HS and Above can be explained by the Poverty Rate.**Conclusion:**This analysis highlights a strong inverse relationship between poverty rates and high school education attainment. As poverty increases, the percentage of adults with high school diplomas decreases, suggesting that higher poverty may be linked to lower educational achievement.

International experience around the world is important in our culture of globalization. According to NAFSA, 54.5% of all American students traveling abroad went to Europe in the 2014-2015 academic year. To determine if there is shift in the proportion of students traveling to Europe, suppose a random sample of 300 students who had studied abroad was taken for the 2015-2016 school year. One-hundred sixty of the students traveled to Europe. a. Conduct a test to determine if the proportion of students traveling to Europe has changed. Be sure to provide a complete write-up. b. Based on the hypothesis test, would you expect 0.545 to be in confidence interval for the proportion? Explain without constructing the interval.
