    a) 0.0066

    (b) 0.0446

    (c) 0.6591

    (d) 0.5000

    Step-by-step explanation:

    a) More than a z-score of 2.48

    P (Z>2.48) = 1-P (Z<2.48)

    =1-0.993431

    Area = 0.006569≈0.0066

    (b) More than a z-score of 1.7

    P (Z>1.7) = 1-P (Z<1.7)

    =1-0.955435

    Area = 0.044565≈0.0446

    (c) More than a z-score of - 0.41;

    P (Z>-0.41) = 1-P (Z<-0.41)

    =1-0.340903

    Area = 0.659097≈0.6591

    (d) More than a z-score of 00

    P (Z>0.00) = 0.5000
