Question

The area under the normal curve between the mean and a score for which z= - 1.20 is

Answer 1

Answer: e. 0.3849

Step-by-step explanation:

We know that the mean lies exactly at the middle of the normal curve .

The z-score of the mean value is 0.

Also According to the standard normal probability table, the probability value of z=0 is P(z<0)=0.5.

And the probability value of z=-1.20 is P(z<-1.2) =0.1150697.

Now, the  area under the normal curve between the mean and a score for which z= - 1.20 is  given by :-

$P(z$

Hence, the area under the normal curve between the mean and a score for which z= - 1.20 is 0.3849 .
