Complete the hypothesis test: null hypothesis = 52, alternative hypothesis =<52, a=0.01 usin data set 45,47,46,58,59,49,46,54,53,52,47,41

  • statistics -

    t = (mean1 - mean2)/standard error (SE) of difference between means

    SEdiff = √(SEmean1^2 + SEmean2^2)

    SEm = SD/√(n-1)

    Since only one SD can be calculated, you can use just that to determine SEdiff.

    Consult your t-test table in the back of your stat book to determine the probability for df = 11.
