Explanation / Answer

a.

P(Z<1.01) = 0.8438 ..............Using Excel function =NORMSDIST(1.01) we will ge 0.8438

b.

P(Z>-0.23)=1-P(Z<-0.23)=1-0.4090=0.5909

c.

P(-0.23<Z<0)=P(Z<0)-P(Z<-0.23)=0.5-0.4090=0.09095

d.

P(-0.23<Z<1.01)=P(Z<1.01)-P(Z<-0.23)=0.8438-0.4090=0.4347

Hope this will be helpful thanksa nd God Bless you :-)
