Find the critical value(s) and rejection region(s) for the indicated t-test, level of significance
alphaα,
and sample size n.
LeftLeft-tailed
test,
alphaαequals=0.100.10,
nequals=28
Homework Answers
Solution :
Given that,
Left tailed test
sample size = n = 28
Degrees of freedom = df = n - 1 = 27
= 0.100
t
,df = t 0.10 , 27 = -1.314
Critical value = -1.314
Rejection region : t < -1.314
