Question

The accompanying table shows the number of millionaires (in thousands) and the population (in hundreds of thousands) for 10 states. Complete parts a through e. Click the icon to view the data table. a. Without doing any calculations, predict whether the correlation and slope will be positive or negative. Explain your prediction. The correlation and slope will be positive because states with a larger population tend to have a larger number of millionaires. b. Make a scatterplot with the population (in hundreds of thousands) on the x-axis and the number of millionaires (in thousands) on the y-axis. Choose the correct scatterplot below. Data Table State Millionaires Population 1 85 34 2 16 8 3 21 13 4 141 65 5 24 12 6 205 86 7 367 193 8 227 123 9 19 10 10 10 6 c. Find the numerical value for the correlation. The correlation is .993 . (Round to three decimal places as needed.) d. Find the value of the slope and explain what it means in context. Be careful with the units. The slope is . This slope indicates that for every increase of one hundred thousand in population, the number of millionaires will increase, on average, by thousand. (Round to four decimal places as needed.)
