Question

Find the area under the standard normal curve that lies between z = -1.84 and z = 1.98. Note: the graph may not be drawn to scale.

Write only a number as your answer. Round to 4 decimal places (for example 0.6148). Do not write as a percentage.

Answer 1

Solution :

Given that,  

Using standard normal table ,

P(-1.84 < z < 1.98)

= P(z < 1.98) - P(z < -1.84)

= 0.9761 - 0.0329

= 0.9432

The area under the standard normal curve that lies between z = -1.84 and z = 1.98 is 0.9432
