What is the area under the normal curve between z = -2.3 and z = 0.08

Solutions

Expert Solution

To find the area under normal curve between z = -2.3 and z = 0.08

We know that the area under a curve is nothing but the probability. Hence, area under normal curve between z = -2.3 and z = 0.08 is P(-2.3 < Z < 0.08)

....since, P(a<X< b) = P(X<b) - P(X<a)

.... since, P(X<-a) = 1 - P(X<a)

Using the standard normal probability table,

Hence, we get,

Therefore, the area under normal curve between z = -2.3 and z = 0.08 is 0.5212
