    ANOVA

    An experiment is designed to measure the effect of detergent brand and washing cycle time on the
    amount of dirt removed from standard household laundry loads. Four brands and four levels of washing
    cycles are selected for the analysis. The results, in pounds of dirt removed are as follows

    18 20 22 24
    A 0.11 0.13 0.17 0.17
    A 0.09 0.13 0.19 0.18
    B 0.12 0.14 0.17 0.19
    B 0.10 0.15 0.18 0.17
    C 0.08 0.16 0.18 0.20
    C 0.09 0.13 0.17 0.16
    D 0.11 0.12 0.16 0.15
    D 0.13 0.13 0.17 0.17

    At the 0.05 level of significance,

    a. is there effect due to detergent brand?

    b. is there an effect due to washing cycle time?

    c. is there an interaction between detergent and washing cycle time?

    d. Plot the mean amount of dirt removed (in pounds) for each detergent brand for each washing cycle time.
