Answer:
169
Step-by-step explanation:
You need to use a Z-table for this.
There are different tables, in this table i searched for the probability of 97% because that equivalent to the top 3%.
for 0.97, Z = 1.88
The formula of Z is:
[tex]Z = (x-mean)/(st. dev.)[/tex]
Solving x:
[tex]1.88 = (x-150)/10 \\x = 168.8 = 169[/tex]
