Homework Statement
At the 5% level, will the two means be equal ?
Homework Equations
The Attempt at a Solution
I tested the variances and found out that it's very likely that the variances are equal, so this is an assumption we make when we do the second test.
Now, I'm trying to test the means and see if they are equal.
I'm getting confused because this is what I get:
Two Sample t-test
data: Var1 and Var2
t = -2.1372 df=3998 p-value = 0.03264
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
-0.128821801 -0.005552541
sample estimates:
mean of x mean of y
-0.0670763877 0.0001107835
zero is not included in the but my p-value is greater than 2.5% (for a two sided test)...
what do I do in such case ?
my t value is more extreme than at the 2.5%.
I think the p-value I'm given is wrong, is it possible ?
Thanks,
Roni.
