Standard deviation of all sample means

A certain population has a mean of 476 and a standard deviation of 36. Many samples of size 56 are randomly selected and the means calculated.

(a) What value would you expect to find for the mean of all these sample means? (Give your answer correct to nearest whole number.)

(b) What value would you expect to find for the standard deviation of all these sample means?
