    Twenty-four hourly readings of the percent lime concentration are shown below
    Hour %CaO Hour %CaO
    1 0.19 13 0.16
    2 0.13 14 0.15
    3 0.11 15 0.20
    4 0.19 16 0.16
    5 0.16 17 0.14
    6 0.17 18 0.16
    7 0.13 19 0.14
    8 0.17 20 0.10
    9 0.10 21 0.13
    10 01.4 22 0.20
    11 0.17 23 0.26
    12 0.14 24 0.16

    a) Use these 24 values to construct a two-period Moving Average Chart.
    b) The next 12 hourly readings for percent lime are:
    0.01 0.18 0.18 0.20 0.11 0.30 0.21 0.11 0.17 0.18 0.13 0.28
    Plot these values on the continuation of the Moving Average Chart.
    c) What does the Moving Average Chart reveal about this process?
    d) Is the Moving Range Chart a useful addition to the Moving Average Chart?
    e) Which chart is easier to use for these periodic data, the XmR Chart or the Moving Average Chart?
