Solution-1
:coefficient of 
=1.14
Solution-2:
SST=9173.3
Solution-5:
we have
Y^=-19.3-0.0835X1+1.14X2+6.40X3
X1=7,X2=5,X3=3
Substituting in regression eq we get
Y^=-19.3-0.0835*7+1.14*5+6.40*3
Y^= 5.0155
Solution-6:
Residual=observedy-predicted y
we got predicted y as 5.0155
Residual=7-5.0155
Residual=1.9845
Solution-10:
t=-1.11
p=0.291
p>0.05
Fail to reject Ho
OPTION-D
Do not Reject Ho.There is no evidence that X1 is significant to the model.
