    T test

    hi guyZz,
    thr is a Q that I cant understand it....is null hypothesis the mean of 10 samples? plz help me in solving this Q...
    Through microarray experiments, a biologist finds the following light intensity measurements (from 10 randomly sampled individuals) for a particular gene.
    -3.4, -o.6, +1.2, +0.6, +2.1, -0.1, +3.0, -0.5, -0.9, -1.2
    If the gene is highly expressed, then it should have highly positive values, and vice versa. For normal expression levels, the intensity level is close to 0. Use a t-test to test the null hypothesis that expression levels are normal for this particular gene.
