Katelyn Mosley · Answer 1

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
