    Paired t test hypothesis testing

    Testing the effectiveness of strategizing, companies 5 year average stock performance (% increase or decrease) were considered before and after consultant led strategizing sessions were held.

    results

    Before : 10, 12, 8, -5, -1, 5, -3, 16, -2, 13, 17
    After : 12, 16, -2, 10, 11, 18, -8, 20, -1, 21, 24

    alpha : .02

    Was the program effective in increasing stock performance?
    Pvalue?
    Null?
    alternative?


    Thanks

    You gotta show some work here man. .

    At the very least you should be able to set up your null and alternative hypothesis. Do that first, and then we can continue (this way at least we know that you know how to at least START the problem).
