reffering to a standard normal distribution. Find the percentage of the cases falling bellow Z= -1.3

Solutions

Expert Solution

We have to find the probability that P(Z<-1.3) and then we will convert it to percentage.

Note that,

We get phi values from standard normal distribution table.

Therefore,

The percentage of the cases falling bellow Z= -1.3 is 9.68% ( since 0.0968 = 9.68%) (Answer)
