You can put this solution on YOUR website!
Find the two sample means.
Test the Hypotheses:
Ho: u1-u2=0
Ha: u1-u2 is not equal to zero
Determine your critical values (based on your alpha).
Determine the t-value of (x1-bar minus x2-bar).
See if your t-value does or does not fall in the
critical area.
Cheers,
