The standard deviation of the sampling distribution can be calculated using the formula:

Standard deviation of sampling distribution = standard deviation of population / square root of sample size

Plugging in the values:

Standard deviation of sampling distribution = $140 / square root(200)

Standard deviation of sampling distribution ≈ $9.9

Therefore, the standard deviation of the sampling distribution is approximately $9.9.
