A skills test used by a recruiter for a company has a mean score of 91 and a standard deviation of 11. What would be the standard deviation of the sampling distribution of the sample mean if samples of size 94 were taken? Round your answer to three decimal places.

s(X) = s / sqrt(n)

s(X) = 11/sqrt(94) = 1.134563371 [answer]
