Answer:

Step-by-step explanation:
We are given the following in the question:
Population mean = 200
Population standard deviation = 50
Sample size, n = 100
We have to estimate the expected value of the sample mean.
The best point estimate for the sample mean is the population mean.
Thus, we can write:

Thus, the expected value of the sample mean is 200.

Answer:
y = 15/x
Step-by-step explanation:
An inverse proportion has the equation ...
y = k(1/x) . . . . k is the constant of proportionality
__
Solving for k, we find ...
k = xy
The coordinates of the given point can be used to find k:
k = (3)(5) = 15
Then the equation of the graph is ...
y = 15/x
