|x - 42.04| = ±23.24
|x - 42.04| = 23.04 U |x - 42.04| = -23.04
x - 42.04 = 23.04 U x - 42.04 = -23.04
+ 42.04 + 42.04 + 42.04 + 42.04
x = 65.05 U x = 19

P(-3.0 < z < 3.0) = 0.9974
Step-by-step explanation:
Mean = 5
Standard Deviation = 0.25
We need to find P(4.25 <x<5.75)
z = x - mean/standard deviation
z = 4.25 - 5/0.25
z = -3.0
z = x - mean/standard deviation
z = 5.75 - 5/0.25
z = 3.0
So, P(4.25 <x<5.75) P(-3.0 < z < 3.0)
Finding values from the z-score table
P(z<-3.0) = 0.0013
P(z<3.0) = 0.9987
P(-3.0 < z < 3.0)=P(z<3.0) - P(z<-3.0)
P(-3.0 < z < 3.0) = 0.9987 - 0.0013
P(-3.0 < z < 3.0) = 0.9974
