H0: b1>= 0.3
H1:b1<0.3
t*= 5.5857
tc=1.860
should i reject H0???
My decision is do not reject H0 since t*>- tc.
But the notes said should reject H0, since t*> tc.
I don't understand why should reject H0.
If you konw which one is correct, please tell me....since i'm frustrated and i
have test on tue
Thank you very much!

the calculated t* is positive, not negative, that's why i feel confused. is that t* in left tail t test cannot be positive? t*= (0.5091-0.3)/ 0.0357 = 5.857 thank you vey much!
