    From a randomly drawn sample of 7 individuals, the length of the left and right arms was measured (in cm.):

    ———— —- —- —- —- —- —- —- left arm 68 67 70 79 65 70 75 right arm 69 76 69 80 66 73 76 ———— —- —- —- —- —- —- —-

    We want keys H0: μ(left) - μ(right) = 0. counter H1: μ(left) - μ(right) < 0. Give the critical value of the one-sided test with risk 0.05.


    1. FALSE: 2.44
