onsider the following Give your answers correct to four deci

onsider the following. (Give your answers correct to four decimal places.) (a) Find P(-2.01 < z < 0.00). b) Find P(-1.77 < z < 2.03). (c) Find P(z < -1.42). (d) Find P(z < -0.59).

Solution

a)P(-2.01<z<0.00)=P(z<0.00)-P(z<-2.01)=0.5-0.0222=0.4778

b)P(-1.77<z<2.03)=P(z<2.03)-P(z<-1.77)=0.9788-0.0384=0.9404

c)P(z<-1.42)=0.0778
