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.

e. Explain why interpreting the value for the intercept does not make sense in this situation.
OA. 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.
OB. 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.
OC. 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.
