Answer:
Part A:
n=196.66≅197 employees
Part B:
n=503.45≅503 employees
Step-by-step explanation:
Part A:
The formula we are going to use to find a sample size is gien below::

Where:
n is the sample size
Z is the distribution
S is the standard deviation
E is the margin
S=341, E=40
Z is calculated as:
Alpha=1-0.90
Alpha=0.1
Alpha/2=0.1/2
Alpha/2=0.05
From Standard distribution table Z at Alpha/2 is 1.645

n=196.66≅197 employees
Part B:
S=341, E=25, Z=1.645

n=503.45≅503 employees
