In: Statistics and Probability
To Test :-
H0 :-
H1 :-
Test Statistic :-
t = 3.6502
Test Criteria :-
Reject null hypothesis if
DF = 36
Result :- Reject Null Hypothesis
Decision based on P value
P - value = P ( t > 3.6502 ) = 0.0008
Reject null hypothesis if P value <
level of significance
P - value = 0.0008 < 0.01 ,hence we reject null hypothesis
Conclusion :- Reject null hypothesis
Confidence interval :-
Lower Limit =
Lower Limit = 1.4279
Upper Limit =
Upper Limit = 9.7721
99% Confidence interval is ( 1.4279 , 9.7721 )
