    See the attached is an excel spreadsheet with the necessary information to complete the problem.

    I am doing a study on alcohol consumption between males and females (two independent samples continuous outcome)this is my hypothesis:

    H1: = Men are able to consume more alcoholic beverages than women
    Ho:= Men and women are able to consume the same amount of alcoholic beverages (no difference).

    I need the STEP BY STEP calculations and solutions to the following questions:

    1. Confidence Interval
    pooled variance
    poole std
    difference in means
    standard error

    2. Test the hypothesis. Please use the Z test.

    3. State the Hypothesis Formally and Informally

    4. Conclusion
