    Answer:

    Mean = 151

    MAD = 9.14

    Step-by-step explanation:

    Given the data:

    135, 160, 145, 155, 170, 150, 142

    Mean = Σx / n

    Mean = 1057 / 7

    Mean = 151

    Mean absolute DEVIATION (MAD) : Σ(x – μ) / n

    [(135-151) + (160-151) + (145-151) + (155-151) + (170-151) + (150-151) + (142-151)] / 7

    Mean absolute deviation = 9.14
