Answer:
The z-scores are
and 
Step-by-step explanation:
From the question we are told that
The middle of the distribution area considered is 48%
Now the rest of the area under the standard normal distribution area is mathematically evaluated



Now to obtain the area occupied by this proportion at the two tails we divide by 2 i.e

Now the z-score is obtained from the normal distribution table and the value is

The
shows that we are considering the two-talil
