Question
Provided below are summary statistics for independent simple random samples from two normal populations. Conduct the required hypothesis test
x1=13,
s1=2.2,
n1=19,
x2=15,
s2=2.1,
n2=19
Two-tailed test,
α=0.01
First, what are the correct hypotheses for a two-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
Next, compute the test statistic.
t=?
(Round to three decimal places as needed.)Finally, determine the P-value.
p-value=?
(Round to four decimal places as needed.)What is the conclusion of the hypothesis test?
Since the P-value is (equal to or less) (greater) than α, (reject) (do not reject) H0.
