Find the area under the standard normal curve to the left of

Find the area under the standard normal curve to the left of z = 2.38. Round your answer to four decimal places, if necessary.

Solution

So if here Z denotes the standard normal variable then we are looking for P[Z<-2.38] Now use command \"NORMSDIST(-2.38)\" in excel to get the required value which is P[Z<-2.38]=.0087
