A slope test computes t = 3.5 with df = 20. The conclusion at α = 0.05 is
A.reject H0 because 3.5 exceeds the critical value
B.fail to reject H0
C.the slope is proven zero
D.the test is invalid
Explanation
Core Concept
t this large is significant.
Correct Answer
Areject H0 because 3.5 exceeds the critical value
