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)

Answer 1

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.
