-Based on the Excel output in Figure 5.1,you should conclude that a

A) $1 million increase in real defense expenditures is estimated to be associated with a statistically significant $1,273.29 billion increase in real GDP,holding all else constant.
B) real GDP is estimated to be a statistically significant $1,273.29 billion when real defense expenditures are 0,holding all else constant.
C) $1 million increase in real defense expenditures is estimated to be associated with a statistically insignificant $13.659 million increase in real GDP,holding all else constant.
D) a $1 million increase in real defense expenditures is estimated to be associated with a statistically significant $13.659 million increase in real GDP,holding all else constant.
