Mean, standard error of mean

[summertigger]

Bank officials claim that the average amount of money in savings accounts at all branches of the Commerce Bank is $7500, with a standard deviation of $650. Many random samples of size 100 are taken. Find:

a)the mean of these samples
b)the standard error of the mean

a) u= 7500
o=650
n=100

[JohnM]

(b) std error of the mean is the std dev divided by the square root of n

[summertigger]

So b) is 65

How am I supposed to find the mean of the samples when there arent any samples?

[JohnM]

the mean of the samples will be equal to the mean of the population

[summertigger]

So the mean of the samples would be 7500?
