find the corresponding area between z= 0 and each of the following
1. z= 0.85
2. z= 1.27
3. z= 2.86
4. z= -1.05
5. z= -2.96
Solution:
(a) "P(0\\le z\\le 0.85)=P(z\\le0.85)-P(z\\le0)=0.80234-0.50=0.30324"
(b)"P(0\\le z\\le 1.27)=P(z\\le1.27)-P(z\\le0)=0.89796-0.50=0.39796"
(c) "P(0\\le z\\le 2.86)=P(z\\le2.86)-P(z\\le0)=0.99788-0.50=0.49788"
(d)"P(-1.05\\le z\\le 0)=P(z\\le0)-P(z\\le-1.05)"
"=P(z\\le0)-[1-P(z\\le1.05)]=0.85314+0.50-1=0.35314"
(e)"P(-2.96\\le z\\le 0)=P(z\\le0)-P(z\\le-2.96)"
"=P(z\\le0)-[1-P(z\\le2.96)]=0.99846+0.50-1=0.49846"
