You wish to test the following claim (H1H1) at a significance
level of α=0.005α=0.005.
Ho:μ1=μ2Ho:μ1=μ2
H1:μ1>μ2H1:μ1>μ2
You believe both populations are normally distributed, but you do
not know the standard deviations for either. However, you also have
no reason to believe the variances of the two populations are not
equal. You obtain the following two samples of data.
Sample #1  Sample #2  



What is the critical value for this test? (Report answer accurate
to three decimal places.)
critical value =
What is the test statistic for this sample? (Report answer accurate

The test statistic is...
This test statistic leads to a decision to...
As such, the final conclusion is that...
The statistical software output for this problem is :
critical value = 2.921
Test statistics = 1.172
The test statistic is not in the critical region
