    Hi,

    My question is in the nonparametric context.

    A pharmaceutical company is interested in studying the effectiveness of
    3 doses of a drug on lowering cholesterol. A total of 4 patients are
    randomly assigned to the doses: 2 to the low dose and I each to the
    medium and high doses, see data table below. The table entries are the
    reduction in cholesterol.

    low medium high
    -----------------------------
    2 4 2
    3

    I know I can use Kruskal-Wallis Test to test the

    H0: miu 1 = miu 2 = miu 3
    Ha: not H0

    But how to test this hypothesis?

    H0: miu 1 = miu 2 = miu 3
    Ha: miu 1 <= miu 2 > = miu 3

    Please help. Thank you!

    Jerry
