The average weekly pay for young adults working a part-time retail job is $480 with a standard deviation of $140. A survey was conducted for a sample of 200 young adults. What is the standard deviation of the sampling distribution? Round the answer to the nearest tenth.(1 point)
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.
