# Statistics: Two or More Sample Hypothesis Testing

** Please see the attached file **

I need assistance in understanding how to work statistics problems.

I need help to specify the Null and Alternative Hypothesis (at least 350 words) based on the Population 1 and 2 in Excel spreadsheet that I have attached.

I need step by step details (Null and Alternative Hypothesis) of how work was done in words of interpretation (that helps explain the results and what it represents) and in EXCEL so that I can understand these types of problems in future problems.

State the Research Question: Is there a notable difference in the performance of pitchers in the American League and the National League (as defined by the ERA) of Major League Baseball because of the DH Rule?

When using Excel please indicated formulas used, thank you.
