Answer: mean of sampling distribution of means = 18.6
Step-by-step explanation:
In sampling theory, the population mean is expected to equal to the mean of sampling distribution of means if the estimator is to be a good representative of the population. so, on this note, the mean of sample distribution of means is equal to the population mean = 18.6
The point-slope form:

We have the points (-5, -2) and (1, 2). Substitute:

Let the number of $1 bill be x and $5 bill be y
x=5y
5y+y=48
6y=48
x=40
y=8
number of $1 bill= 40
number of $5 bill = 8
