Answer:
Their welders earn $50,000 annually.
Step-by-step explanation:
Given : 

n = 100

To Find : The ship building association wishes to find out whether their welders earn more or less than $50,000 annually.
Solution :

n = 100
Since n > 30
So we will use z test

Substitute the values


Refer the z table for p value
p value = 0.9599
α= 0.05
Since p value > α
So we accept the null hypothesis .
Hence their welders earn $50,000 annually.
