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
because states with a larger population will most likely have a
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.

![c. Find the numerical value for the correlation.
The correlation is
(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.)
e. Explain why interpreting the value for the intercept does not make sense in this situation.
O A. In this situation, the intercept would be the population of a state that had no millionaires. Since there are no states in the given data with no millionaires, the intercept would not make any sense.
O B. In this situation, the intercept would be the population at which everyone in the state would be a millionaire. Since it is unreasonable to assume that everyone in the state is a millionaire, the
intercept does not make any sense.
O C. In this situation, the intercept would be the number of millionaires that live in a state with a population of zero. Since there would be no population in the state, then any number of millionaires
besides zero would not make sense.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff0c1ca81-963e-4668-a5af-b3c412b423c8%2F406fc68c-a61b-4b66-977e-22597fce1fe2%2Ft6z05hs_processed.png&w=3840&q=75)
