Answer:
Sample size is 16
Mean 4
Standard deviation of the sample is 0.3.
Explanation
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
 and standard deviation 
, a large sample size can be approximated to a normal distribution with mean 
 and standard deviation 
.
In this problem, we have that:
The population has a mean of four hours, with a standard deviation of 1.2 hours. The sample is the 16 of the employees.
So
The sample size is 16, so 
The mean of the sample is the same as the population mean, so 
.
The standard deviation of the sample is 
 
        
             
        
        
        
 In Cafeteria plan plans, the employer allocates a certain amount of money to each employee and lets the employee spend that money for benefits that suit him or her. 
<h3>Work of Cafeteria Plan</h3>
Although it has nothing to do with food, a cafeteria plan receives its name from a cafeteria. Before payroll taxes are calculated, employees can select the benefits of their choosing from a pool of possibilities supplied by their employers, just like people make meal choices in cafeterias. As workforce diversity increases and workers look for more individualized benefits that are catered to their requirements, these plans become increasingly beneficial.
The insurance choices available under cafeteria plans include contributions to health savings accounts (HSAs), group term life insurance, and disability insurance.

Resource renewal is the process through which an economy's production possibilities curve shifts outward.
<h3>What is the production possibilities curve?</h3>
It is a graph that shows the possibility of production of two commodities when resources are fixed. It occurs when the resource for manufacturing a product is limited.
When the curve is shifted outward or outside it indicates that there is a need for resources to be renewed.
Therefore, Resource renewal occurs when the economy's production possibilities curve shifts outward.
