The test -Conclusion at &=.05

t= (to 2 decimal places.)

-value is - Select your answer -less than .01between .01 and .025between .025 and .05between .05 and .1greater than .1Item 2

b. Test for a significant relationship using the test F.
P-value is - Select your answer -less than .01between .01 and .025between .025 and .05between .05 and .1greater than .1Item 4

What is your conclusion? Use & = .05

Because P-value is [- Select your answer -greater than or equal to less than or equal to equal to] .05 , we [- Select your answer -accept/reject] H₀ : B₁ is [- Select your answer -greater than or equal to zero less than or equal to zero equal to zero].
