Answer:  a) 27.5, b) 5.33.
Step-by-step explanation:
Since we have given that 

and n = 180
We need to calculate the sample mean and sample standard deviation.
So, the mean of the distribution of sample means is 

The standard deviation of the distribution of sample means is 

Hence, a) 27.5, b) 5.33.
 
        
             
        
        
        
Answer:
B. f(x) = 4 log(x+3)
Step-by-step explanation:
B. f(x) = 4 log(x+3) : shifted three units to the left of g(x) = 4 logx
