Claim: u1 > u2, a=0.10, sample statistics: x1= 500, s1= 30, n1=100 and x2=510, s2=15 and n2= 75.

With the question above I need to find the test statistics, the standardized test statistics, decide whether the standardized test statistic is in the rejection region and decide whether you should reject or fail to reject the null hypothesis.

I'm not sure to get find any of these answers and I sent my teacher an email for help but still no response and I need to figure this out by sat. So can anyone help please thank you.
