Given the following information about a hypothesis test of the difference between 2 means based on independent random samples, what is the correct rejection region at a significance level of .05?

Ha: Ua> Ub
x1-112, x2=9
s1=4, s2=2
n1=13, n2=10

Solution Preview

I assume that your given information is

Ha: Ua> Ub

x1=12, x2=9
s1=4, s2=2
n1=13, n2=10

*******************************************

This is a one-tailed test ...

Solution Summary
