The standard deviation of the sampling distribution can be calculated using the formula:
Standard deviation of sampling distribution = Standard deviation of population / sqrt(sample size)
Plugging in the values:
Standard deviation of sampling distribution = 140 / sqrt(200)
= 140 / 14.14
= 9.9
Therefore, the standard deviation of the sampling distribution is approximately 9.9.
