a-1.How many explanatory variables were specified in the model?

a-2.How many observations were used?

b.Choose the hypotheses to determine whether the explanatory variables are jointly significant.

  • H0:1=2= 0;HA: At least onej> 0
  • H0:1=2= 0;HA: At least onej 0
  • H0:1=2= 0;HA: At least onej< 0

c.Compute the value of the test statistic.(Round your answer to 3 decimal places.)

d-1.Find thep-value.

p-value < 0.01

d-2.At the 5% significant level, what is the conclusion to the test?

RejectH0; the explanatory variables are jointly significant.
