Answer:

175

Step-by-step explanation:

The sample size n in<em> Simple Random Sampling</em> is given by

$\bf n=\frac{z^2s^2}{e^2}$

<em> where z = 1.96 is the z-score associated with a 95% confidence level ans s the standard deviation. </em>

Replacing values

$\bf n=\frac{(1.96)^2(675)^2}{(100)^2}=175$

So, there should be 175 chief executive officers in a sample if we want to estimate the population mean annual salary plus bonus with a margin of error of $100,000
