Suppose α = 0.01. Which of the following represents the correct conclusion?
To Test :-
H0 :-
H1 :-
Test Statistic :-
t = -1.6522
Test Criteria :-
Reject null hypothesis if
DF = 243
Result :- Fail to Reject Null Hypothesis
Decision based on P value
P - value = P ( t > 1.6522 ) = 0.0499
Reject null hypothesis if P value <
level of significance
P - value = 0.0499 > 0.01 ,hence we fail to reject null
hypothesis
Conclusion :- We Accept H0.
There is insufficient evidence to support the claim that Japanese managers are more motivated than American managers using the Sarnoff Survey of Attitudes Toward Life (SSATL).
