Answer:
5 EXP x 50 Monsters = 250 EXP
Step-by-step explanation:
 
        
             
        
        
        
Part a)
The simple random sample of size n=36 is obtained from a population with 

and 

The sampling distribution of the sample means has a mean that is equal to mean of the population the sample has been drawn from.
Therefore the sampling distribution has a mean of 

The standard error of the means becomes the standard deviation of the sampling distribution.

Part b) We want to find 

We need to convert to z-score.

Part c)
We want to find 

We convert to z-score and use the normal distribution table to find the corresponding area.

Part d) 
We want to find :

We convert to z-scores and again use the standard normal distribution table.

 
        
             
        
        
        
The y intercept is when x=0 so y=1/2(0) -3 so y=0-3 so y=-3
