Find the area under the standard normal curve that lies outside the interval bet

Question

Find the area under the standard normal curve that lies outside the interval between z = -1.77 and z = 2.14. Write only a number as your answer. Round to 4 decimal places (for example 0.6148). Do not write as a percentage. Find the area under the standard normal curve that lies between z = -1.48 and z = 1.98. Write only a number as your answer. Round to 4 decimal places (for example 0.6148). Do not write as a percentage. Find the area of the shaded region where a = -0.74 and b = 2.12. Write only a number as your answer. Round to 4 decimal places (for example 0.6148). Do not write as a percentage.

Explanation / Answer

5) z=2.14 = p(z=2.14)=0.9838 from standard z table the value

z=-1.77=p(z=-1.77)= 0.0384 from z table

area is 0.9838-0.0384=0.9454

b) z =1.98=p(z=1.98)=0.9761

z=-1.48=p(z=-1.48)=0.0694

area is 0.9761-0.0694=0.9067

c) same like above two b=2.12 p(b=2.12)=0.9830

a= -0.74=p(a=-0.74)=0.2296

area =0.9830-0.2296=0.7530
