Question 437263: use the given sample statistic to test teh claim about the difference between 2 Population means U1 and U2. at the given level of significance alfa. samples are random /independent. the populations are normally distributed.
claim: U1=U2 i dont understand??
alfa: .05
x1: 300
S1: 26
N1: 19
x2: 290
S2: 22
N2: 12 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! use the given sample statistic to test the claim about the difference between 2 Population means U1 and U2. at the given level of significance alfa. samples are random /independent. the populations are normally distributed.
Ho: u1-u2 = 0 (claim)
Ha: u1-u2 is not 0
================================
claim: U1=U2 i dont understand??
alfa: .05
x1: 300
S1: 26
N1: 19
x2: 290
S2: 22
N2: 12

I ran a 2-Sample T-test on a TI calculator and got the following:
test stat: t= 1.1477
p-value = 0.2614
df = 26.41
----
Conclusion: Since the p-value is greater than 5%, fail to reject Ho.
The claim is supported by the test results.
