The standard error of the mean (SEM) can be calculated using the formula: SEM = σ/√n, where σ represents the population standard deviation and n represents the sample size. Plugging in the given values, we get:

SEM = 18/√9 = 6

Therefore, the standard error for the distribution of sample means is 6.
