x1=21,
s1=3,
n1=21,
x2=25,
s2=4,
n2=17
Left-tailed test,
α=0.05
What are the correct hypotheses for a left-tailed test?
H0: μ1=μ2
Ha: μ1≠μ2
H0: μ1>μ2
Ha: μ1=μ2
H0: μ1=μ2
Ha: μ1>μ2
H0: μ1<μ2
Ha: μ1=μ2
H0: μ1≠μ2
Ha: μ1=μ2
H0: μ1=μ2
Ha: μ1<μ2
Compute the test statistic.
t=?
(Round to three decimal places as needed.)Determine the P-value.
p-value=?
(Round to four decimal places as needed.)Since the P-value is
(equal to or less) (greater) than α, (reject) (do not reject) H0.
