Answer 1

Let me answer some of the questions for you-

15) Based on the output, the regression output can be given as follows-

Y = 30.99 + 0.961*X1 + 0.334*X2

16) For multiple regression, the test statistic used is: F-value

17) F Critical at 5% level of significance for 10 degrees of freedom is given from the F-table as

F Critical = 2.98 which will be (a)

19)

Ho: Null Hypothesis will be: b1=b2=0

20) X1 = 45 and X2 = 200

Y = 30.99 + 0.961*45 + 0.334*200 = 141.03
