The estimated regression equation was ŷ = 83.2 + 2.29x, + 1.30x2.

How do I put this in a scatter plot with per-capita real GDP in 1960 (relative to the USA in 1960) on the horizontal axis and the average per-capita growth rate of GDP on the vertical axis? Also when you hover over the separate points would it show what the country code is?
Hi Expert, I need help. Thanks Judge and Cable (2010) report the results of a study demonstrating a negative relationship between weight and income for a group of men. Following are data similar to those obtained in the study. To simplify the weight variable, the men are classified into five categories that measure actual weight relative to height, from 1 = thinnest to 5 = heaviest. Income figures are annual income (in thousands), rounded to the nearest $1,000. Weight Income 4 151 5 88 3 52 2 73 1 49 3 92 1 56 5 143 These data show a positive relationship between weight and income for a sample of men. However, weight was coded in five categories, which could be viewed as an ordinal scale rather than an interval or ratio scale. If so, a Spearman correlation is more appropriate than a Pearson correlation. Convert the weights and the incomes into ranks and complete the table that follows. Ranks X Y XY 8 7 6…

3. Consider the following sets of data from Dataset II. For the dataset, determine what type of chart or graph would best represent those data (A-D). Explain your reasoning in detail. Pie chart Line graph Bar graph Scatter plot Dataset II: Carolyn collected data on rates of recycling participation over the last eight years to determine whether her city’s education program has been effective. In 2006, before the education program was implemented, 9% of the city’s residents recycled.

Use this dataset for your analysis software.Cost-to-charge ratio (the percentage of the amount billed that represents the actual cost) for inpatient and outpatient services at 11 Oregon hospitals is shown in the following table. A scatterplot of the data is also shown. Cost-to-Charge Ratio Hospital OutpatientCare InpatientCare 1 62 80 2 66 76 3 63 75 4 51 62 5 75 100 6 65 88 7 56 64 8 45 50 9 48 54 10 71 83 11 54 100 The least-squares regression line with y = inpatient cost-to-charge ratio and x = outpatient cost-to-charge ratio is = -1.1 + 1.29 x. (a) Is the observation for Hospital 11 an influential observation? Yes or No (b) Is the observation for Hospital 11 an outlier? Yes or No (c) Is the observation for Hospital 5 an influential observation? Yes or No (d) Is the observation for Hospital 5 an outlier? Yes or No
