During the $1990$ s$,$ investors made investment decisions based on market performance. As the nature of investing shifted $($more day traders and faster flow of information using technology$),$ the relationship between market performance $($Return$)$ in percent and money flowing $($Flow$)$ into mutual funds $($ $ million$)$ shifted. The least squares linear regression is shown below. Complete parts a through $d.($You may assume that the assumptions and conditions for regression are met.$)$

widehat$($ Flow $)=9316+719$ Return

a$)$Interpret the intercept in the linear model. Choose the correct answer below.

A$.$ The intercept is the actual value of the money Flow if the Return was $0\%.$

B$.$ The intercept is the predicted value of the Return if the money Flow was $$0.$

C$.$ The intercept is the predicted value of the money Flow if the Return was $0\%.$

D$.$ The intercept is the actual value of the Return if the money Flow was $$0.$

b$)$Interpret the slope in the linear model. Choose the correct answer below.

A$.$ Fund Return increases by $$719$ million for every $1\%$ increase in money Flow.

B$.$ Money Flow increases by $$719$ million for every $1\%$ decrease in fund Return.

C$.$ Money Flow increases by $$719$ million for every $1\%$ increase in fund Return.

D$.$ Fund Return increases by $$719$ million for every $1\%$ decrease in money Flow.

c$)$ What is the predicted fund Flow for a month that had a market Return of $0\%?$

The predicted fund Flow is $ million.

d$)$ If during this month, the recorded fund Flow was $$5$ billion, what is the residual using this linear model? Did the model provide an underestimate or overestimate for this month?

for this month.
