The mean distance freshman students live from campus is 135.0 miles with a standard deviation of 13.0 miles. Random samples of 34 freshmen are taken from the freshman class.

What is the mean of the sampling distribution of the sample means? (round to 1 decimal place). mu subscript x with bar on top end subscript =

What is the standard error of the mean? (round to 2 decimal places). sigma subscript x with bar on top end subscript =

What is the probability that the sample mean is less than 130 miles? (round to 3 decimal places).
