Question

A researcher interested in explaining the level of foreign reserves for the country of Barbados
estimated the following multiple regression model using yearly data spanning the period 2001 to
2016:
??=?+????+????+????
Where FR = yearly foreign reserves ($000’s), OIL = annual oil prices, EXP = yearly total exports
($000’s) and FDI = annual foreign direct investment ($000’s). The sample of data was processed
using MINITAB and the following is an extract of the output obtained:

Predictor   coef         StDev           t-ratio          p-value
constant    5491.38      2508.81    2.1888              0.0491
oil              85.39          18.46          4.626             0.0006
exp           -377.08         112.19           *                 0.0057
fdi             -396.99          160.66         -2.471           **

S=2.45       R-sq=96.3%         R-sq(adj) =95.3%

source              Df        ss            ms           f      P
Regression        3       1991.31      663.77     ?   ??
Error               12          77.4           6.45
Toal                15

What is dependent and independent variables? 
 Fully write out the regression equation 
 Fill in the missing values ‘*’, ‘**’, ‘?’and ‘??’
