Answer:
[tex]\bar{x}= 200[/tex]
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:
[tex]\bar{x}= \mu = 200[/tex]
Thus, the expected value of the sample mean is 200.
