A sample of 90 people is taken from a population. The standard deviation of the sample is 34.4. What is the approximate value of the standard error of the sampling distribution? Round your answer to two decimal places.
A. 2.53
B. 3.64
C. 4.73
D. 5.83
B. 3.64
To calculate the standard error of the sampling distribution, divide the standard deviation of the sample by the square root of the sample size.
Standard error = 34.4 / sqrt(90)
Standard error ≈ 34.4 / 9.49
Standard error ≈ 3.64
So, the approximate value of the standard error of the sampling distribution is 3.64.
