Answer:
Atleast 315
Step-by-step explanation:
Given that a journalist wants to determine the average annual salary of CEOs in the S&P 1,500. To save time a sample is taken.
s = sample std dev = 449300
Sample size = n
Margin of error = 50000
Z critical = 1.96
Hence 1.96*std error = 50000
std error = 25510.20
Std deviation/sqrt n = 25510.20
Simplify to get

So sample size should be atleast 315
