    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.

    When using Excel please indicated formulas used, thank you.
